Many here have had or have what your describing but it could be something else like PF (Plantar Phascitis) or TS (Tarsal Tunnel). I've 3 surgeries on my feet to help with the pain before I learned it was PN. You can find a podiatrist to help but be careful if they are surgoens they might what to cut and then ask questions. You can have a nerve conduction test as well from a neuro to help narrow it down. Things like activity, your weight can effect heel pain. You can go here and talk with those who suffer with heel pain.
