Dr. Tom on the critical difference — tendinitis is inflammation, tendinosis is degeneration. Treatment differs.

In Our Clinic

Most Achilles tendonitis patients we see at Balance Foot & Ankle are recreational runners in their 40s or 50s who ramped up mileage too quickly, plus a second cohort of middle-aged women who recently switched from heels to flat shoes. The first question we ask is whether the pain is at the insertion on the heel bone versus 2–6 cm up the mid-substance — the treatment ladder is genuinely different. Eccentric heel-drops, heel lifts, and a soft-strike gait retraining pass resolve ~80 % of cases. The ones who aren’t improving by week 8 usually have an unrecognized Haglund’s deformity or insertional calcific tendinosis that needs imaging.

Achilles Tendinitis Surgery 2 - Balance Foot & Ankle

When to See a Podiatrist

Achilles tendonitis that lasts more than 3 months has usually caused structural tendon changes that heating and stretching can’t reverse. Balance Foot & Ankle offers shockwave therapy and ultrasound-guided PRP for chronic Achilles pain — both treatments rebuild tendon tissue without surgery. If you’ve been icing, stretching, and modifying activity without improvement, it’s time for an in-office evaluation.

Frequently Asked Questions

Which is better for plantar fasciitis?

The shoe with more cushioning and a stronger rocker typically wins for plantar fasciitis. See full comparison for our specific verdict.

Which lasts longer?

Both options typically last 300-500 miles for runners or 9-12 months for daily walkers. Material durability varies; check our detailed comparison.

Which is better for flat feet?

Flat feet need stability or motion control. The neutral option is not ideal unless paired with a custom orthotic.

More questions patients ask

How long does an ankle sprain take to heal?

Recovery time depends on severity: Grade 1 (mild stretching) typically heals in 1-3 weeks, Grade 2 (partial tear) in 3-6 weeks, and Grade 3 (complete tear) in 6-12 weeks or longer. Proper rehabilitation is critical to prevent chronic ankle instability, which affects up to 40% of patients who don't receive adequate treatment. Dr. Biernacki creates customized recovery plans.

When should I see a doctor for a sprained ankle?

Seek professional evaluation if you can't bear weight, notice significant swelling or bruising, hear a pop at the time of injury, have numbness, or if pain hasn't improved after 5-7 days of RICE treatment. X-rays or MRI may be needed to rule out fractures. Dr. Biernacki offers same-day urgent evaluations at 810-206-1402.

Can a sprained ankle heal without treatment?

While mild sprains may heal with rest and home care, undiagnosed ligament tears and improperly rehabilitated sprains frequently lead to chronic ankle instability, recurrent sprains, and early-onset arthritis. A proper evaluation ensures appropriate treatment and reduces your risk of long-term complications significantly.
