injection therapy
Injection therapy is an effective non-surgical treatment option for a wide range of foot and ankle conditions. By delivering targeted treatment directly to the affected area, injections reduce pain, decrease inflammation, promote tissue healing, and restore function.
At Flex Foot & Ankle Center, injection therapy is integrated into a personalized treatment plan tailored to each patient’s condition — whether it’s a sports injury, chronic pain, or nerve-related disorder.
Regenerative Injection Therapy
Regenerative therapies stimulate the body’s own healing mechanisms to repair damaged tissue, reduce inflammation, and restore function to injured structures of the foot and ankle.
These treatments are indicated for patients seeking non-surgical alternatives or looking to accelerate recovery following injury or surgery.
Amniotic Fluid Injections
Amniotic fluid is composed of growth factors, cytokines, collagen, and hyaluronic acid — substances naturally found in the body that play a key role in tissue repair and regeneration. Derived from the innermost layer of healthy human placenta, it is FDA-regulated and has been used clinically for over a century across burn treatment, wound healing, and musculoskeletal conditions.
How it works: Amniotic fluid exerts anti-inflammatory and antimicrobial effects on surrounding tissue. It provides a natural cellular scaffold that supports the rebuilding of cartilage, tendon, ligament, muscle, and bone — while significantly reducing pain and promoting faster return to full activity.
Conditions treated:
- Plantar fasciitis / heel and arch pain
- Ankle sprains and instability
- Tendonitis (Achilles and others)
- Ligament strains and tears
- Capsulitis / metatarsalgia
- Bunions and hammer toes
- Arthritic toe joints
- Non-healing or delayed-healing fractures
- Sesamoiditis
- Chronic soft tissue injuries
Vitamin B12 (Cyanocobalamin) Injections
Vitamin B12 plays a critical role in nerve regeneration and healthy nerve function. When nerve damage or irritation is present, a concentrated dose of B12 injected directly around the affected nerve has been shown to promote nerve repair and significantly reduce neuropathic pain.
Injections are performed under ultrasound guidance to ensure precise placement and maximize effectiveness.
Conditions treated:
- Peripheral neuropathy
- Sural nerve neuritis
- Neuritis of any superficial nerve in the leg, ankle, or foot
- Morton’s neuroma
- Post-traumatic neuralgia
Why B12 instead of cortisone?
Unlike corticosteroid injections, B12 does not carry tissue-destructive properties. This makes it a safe option for repeated administration and ideal for patients who need conservative, long-term nerve care.

Highly recommend giving her a visit!Posted on Aryeh GamoranTrustindex verifies that the original source of the review is Google. I had a great experience with Dr. Perez. She was extremely attentive to my needs and provided exceptional care and service throughout the process. I highly recommend her to anyone looking for professional treatment with lasting benefits.Posted on Keith FrazierTrustindex verifies that the original source of the review is Google. Dr. Perez has a great personality that’s friendly, engaging and thoughtful. She remembers personal details which add to the personal touch that many physicians lack, especially within any specialty. I thought the absolute worse, that I had fungus or that my foot was going to fall off. Turns out it was eczema, but scared me for sure. She brought my mind to ease and actually prescribed the right thing on the first visit. Highly recommend.Posted on Eric VillegasTrustindex verifies that the original source of the review is Google. Yesterday was my first visit with Dr. Perez. I was impressed by her practice. Very chic, modern and clean. The technology she uses is above par. I was able to receive some test results immediately. The staff is warm and friendly and definitely conveyed empathy and assurance. This was refreshing. The Doctor took her time with the consultation. She was detailed in her explanation and thorough with her diagnosis and prognosis. She allowed for questions and provided detailed replies and options for treatment. At no time did I feel rushed. The doctor spoke with candor about my circumstances and didn't fill me with any false hope. I appreciated her direct approach on how I got to where I am currently. Even though some of the information shared was difficult to hear, I did leave with an optimistic outlook. I look forward to returning for our follow-up visit and the treatment proposed. Thank you Dr. Perez!Posted on Julie NamTrustindex verifies that the original source of the review is Google.

Excellent and comforting bedside manner Explained everything Recommend without reservationPosted on NokkitTrustindex verifies that the original source of the review is Google. Dr. Perez is an excellent foot and ankle surgeon. I recently underwent an ankle arthroscopy with cement injection, PRP injection, and a bunionectomy. I am still healing, but I am extremely grateful that I chose her for this procedure. She is incredibly compassionate, accommodating, and truly detail‑oriented. She listens to her patients with genuine care and gives thoughtful, attentive explanations. Her office is immaculately clean and aesthetically beautiful, which adds to the overall positive experience.

I am truly grateful to have found Dr. Perez.Posted on Jovelle De llamasTrustindex verifies that the original source of the review is Google. I had an excellent experience at Flex Foot & Ankle. I broke my 5th metatarsal and needed surgery to properly align it, and from start to finish, everything went smoothly. Dr. Perez is truly amazing — she is not only highly skilled but also incredibly caring. She treats her patients like family and honestly felt like a mom to me throughout the process. She took the time to explain everything, made sure I was comfortable, and showed genuine concern for my recovery. The clinic itself is very clean and well-organized, and the staff are all kind, professional, and welcoming. The entire surgical process and follow-up care went very well, and I felt supported every step of the way. Thanks to Dr. Perez and her team, my recovery has been great and I’m now able to work properly again.

Injection Therapy FAQs
Have questions about Vitamin B12 and regenerative injection therapy?
Here are answers to some of the most common questions about injection therapy for foot, ankle, and lower leg conditions, including peripheral neuropathy, nerve pain, inflammation, and tissue healing. Learn how these treatments work, who may benefit, and what to expect during the recovery process.
What is peripheral neuropathy and how do B12 injections help?
Peripheral neuropathy results from damage to peripheral nerves, causing burning, tingling, numbness, or shooting pain in the feet and legs. B12 injections support nerve repair and are used as part of a comprehensive treatment plan for patients experiencing neuropathic symptoms.
How does B12 support nerve function?
Vitamin B12 is essential for maintaining healthy nerves and ensuring proper nerve signal transmission. Adequate B12 levels are critical for nerve tissue repair, nerve protection, and overall neurological function.
What symptoms of neuropathy may benefit from treatment?
Patients with neuropathy may experience:
- Burning sensations in the feet
- Tingling or pins-and-needles sensations
- Numbness
- Sharp or shooting pain
- Increased sensitivity to touch
- Weakness in the feet or lower legs
- Difficulty walking or maintaining balance
B12 injections can help address these symptoms when they are associated with nerve dysfunction.
What effects does B12 have on surrounding tissue?
Unlike corticosteroid injections, B12 does not carry tissue-destructive properties. This makes it a safe option for repeated administration and ideal for patients seeking a conservative, long-term approach to nerve pain — without risk of damage to adjacent soft tissues.
What is ultrasound-guided injection therapy?
Ultrasound guidance allows real-time visualization of nerves, tendons, and surrounding structures during the procedure, ensuring the injection is delivered precisely to the intended treatment site for maximum accuracy and effectiveness.
Are B12 injections safe?
Yes. Vitamin B12 is a naturally occurring nutrient essential to nerve health. When administered by a qualified podiatrist, it is well tolerated and does not negatively affect surrounding soft tissue.
