Forefoot Pain, Sesamoiditis, and Ball-of-Foot Conditions in Michigan: Balance Foot & Ankle

Michigan patients with forefoot pain — pain in the ball of the foot, under specific metatarsal heads, or at the 1st MTP joint (big toe joint) — benefit from a podiatric evaluation that establishes the specific diagnosis rather than treating generalized metatarsalgia. Sesamoiditis (inflammation of the sesamoid bones beneath the 1st MTP) requires sesamoid-offloading orthotics and, for severe cases, steroid injection or surgical excision. Metatarsalgia from 2nd-4th metatarsal overload responds to metatarsal pad placement and custom orthotics addressing the mechanical overload pattern. Morton’s neuroma causes burning and numbness into the 3rd and 4th toes and responds to steroid injection and surgical decompression when conservative care fails. Plantar plate injuries at the lesser MTP joints require MRI confirmation and specific orthotic modifications. At Balance Foot & Ankle, Michigan patients with forefoot pain receive a thorough diagnosis with weight-bearing X-rays and ultrasound, and targeted treatment based on the confirmed diagnosis. Call (810) 206-1402 for an appointment at our Howell or Bloomfield Hills office.

Michigan Podiatry for Foot Pain: Getting the Right Diagnosis and Treatment

Michigan patients struggling with ongoing foot pain often find that self-care measures and general advice only go so far without knowing the specific cause. At Balance Foot & Ankle, podiatric evaluation identifies the actual diagnosis — distinguishing plantar fasciitis from Baxter’s nerve entrapment, sesamoiditis from turf toe, hammer toe from claw toe, or metatarsalgia from neuroma — and directs treatment that works for the confirmed diagnosis rather than the most common possible cause. Our fellowship-trained podiatric surgeons provide the full range of conservative and surgical treatment options, and we give honest advice about which approach is most appropriate for each patient’s specific situation. Michigan patients can schedule at Balance Foot & Ankle by calling (810) 206-1402 for our Howell or Bloomfield Hills office — same-week appointments available.

Comprehensive Michigan Foot Care: What to Expect at Balance Foot & Ankle

Michigan patients who choose Balance Foot & Ankle for their podiatric care receive a thorough evaluation that begins with a detailed history of their foot problem — how long it has been present, what makes it better or worse, what treatments have been tried, and how the pain is affecting their daily activity and quality of life. Physical examination includes gait analysis, structural assessment, range of motion testing, neurological screening, and vascular evaluation when indicated. Weight-bearing digital X-rays are obtained at the initial visit when imaging is indicated. Musculoskeletal ultrasound is available for soft tissue characterization. Patients leave their first appointment with a confirmed or strongly suspected diagnosis, a treatment plan, and realistic expectations for recovery. Balance Foot & Ankle accepts Blue Cross Blue Shield of Michigan, Aetna, UnitedHealthcare, Cigna, Medicare, and most Medicare Advantage plans. New patients can call (810) 206-1402 to schedule at our Howell or Bloomfield Hills Michigan office.
