I have tried new orthotics (temporary), but i get burning on the bottom of my feet. because of heel pain, i can't go back to the old ones. plz advise.

Further examination.: It sounds like you need to see a Podiatrist so you can get to the bottom of your problem. There are a lot of questions that need to be asked if it is "heel pain" or plantar fasciitis. Add stretching, ice at night and keep shoes on. If no better, see a Podiatrist. Here is some one you can see,,,,, http://www.drsubotnick.com/ Good luck.
