It didn’t happen at work, school, or exercise, and there haven’t been any trips and/or falls, but you can’t pinpoint what is causing foot and ankle discomfort and sensations. However, the cause could be originating in the lumbar spinal region. Sciatica is a set of symptoms that refer to pain, numbness, and tingling radiating down the leg from the lower back, affecting the legs, hips, buttocks, and feet. Injury Medical Chiropractic and Functional Medicine Clinic can release the compressed nerve, massage circulation back into the nerve, and restore mobility and function.

Sciatica Foot and Ankle
Sciatic nerve sensations can run down the back of the leg down into the foot.
- Compression or irritation to any nerve roots can present with symptoms in the hip, thigh, calf, and foot.
- Sciatica foot and ankle symptoms can accompany numbness and muscle weakness.
- Sciatic nerve irritation mostly causes symptoms on the outside of the foot but can spread to other areas.
Nerve Roots
One or more of the lower spine’s sciatic nerve roots are being compressed or pinched. The foot symptoms location depends on which nerve root is affected.
- If the S1 root is affected, symptoms will radiate to the sole and side of the foot.
- If L5 is affected, symptoms will radiate to the top of the foot and the big toe.
- If the L4 root is affected, symptoms can radiate to the medial or inside the ankle area.
Chiropractic Care and Relief
Foot Massage
A foot massage can be helpful.
- A massage therapist finds points around the ankles that are tender.
- Tenderness indicates a lymphatic blockage or muscle tension that needs to be worked out.
- They will apply varying pressures to massage the muscles and get the circulation flowing.
- The therapist will loosen the tarsal and metatarsal bones to loosen the muscles and nerves.
- Moving the bones resupplies the joints, forces out inflammatory metabolic waste, opens the space for the nerves, and allows improved lymphatic drainage and blood flow to expedite healing.
Nerve Flossing
Nerve flossing exercises can help stretch and maintain the released nerve.
- A chiropractor will perform and train the individual on targeted stretches to the Achilles tendon and plantar fascia.
- They will stretch, release, and open the ankle and sciatic nerve.
Injections
A cortisone injection where the nerve is affected can help in certain cases.
- Injections of a corticosteroid, an anti-inflammatory medicine, can offer relief for up to three months and are given under local anesthesia.
- The medicine reduces the inflammation and swelling around the nerve roots.
Foot Orthotics
- Custom foot orthotics can help support a postural foot or ankle problem.
- Overpronation is when the ankles collapse inward, which creates an imbalance of leg lengths that affects the hips, pelvis, and spine.
- Orthotics can help provide symptom relief.
Nutrition
Part of a treatment plan will include an anti-inflammatory and antioxidant nutritional plan.
- A professional nutritionist will make recommendations based on the individual’s case.
- Magnesium-rich foods are generally recommended for sciatica as this nutrient aids the body in releasing muscle contractions.
- 99 percent of the body’s magnesium is stored in the bones, muscles, and soft tissues, with only 1 percent concentrated in the blood.
Foods rich in magnesium include:
- Avocado
- Bananas
- Apricots
- Dried pumpkin seeds
- Dairy
- Dark chocolate
- Dried figs
- Black beans
- Brown rice
- Fish
- Spinach
- Swiss chard
- Yogurt
