Finally went to the podiatrist this week to seek diagnosis and treatment of pain in the balls of both feet radiating to the third and fourth toes - sure enough, Morton's neuroma in both feet as my cycling friend (who also suffers from this) predicted! Morton's neuroma is an enlargement/thickening of the nerve due to compression and irritation. Got an injection of cortisone and lidocaine to temporarily reduce the swelling, and started physical therapy today (combination of laser, ultrasound, and ice/electrical stimulation). Custom orthotics on order. My doctor knew better to tell me to quit cycling (I average 180 miles per week). The pain becomes unbearable after about 50 miles, so I am trying to balance intensity, hills and mileage so I can keep building and at the same time give this thing a chance to heal. Will also work on my pedaling efficiency. Wondering how frequent this is in cyclists, and if any of you have experienced this, how you fared with treatment. For some reason, I am told this condition is more prevalent in women.
