Podiatrist said my left heel has thinning of the fat pad. tried dr. scholl's p.ro. heel orthotics but it doesn't help much. what else can i try?

Difficult problem: If you truly have a thinned heel pad, it is a tough problem. The best solution is through proper shoe wear (running sneakers are best). Also silicone heel cups should help. Avoid surgery or any type of injections.

Custom Orthotic: You can try a custom orthotics. There are injections of Juvaderm or other fillers but just you know these are off-label, meaning not FDA approved.

Cushioning: you can replace what you don't have anymore with simple padding. Foam rubber is best
