Yep, its where the most heat pours off me and sweat. And now since its gotten cold and my cerculation sp? has gotten worse im now getting sores under my fent patches which never happend befor, but its because im getting poor blood flow in my arms. And I know they say tell your dr if your getting sores from the patch, but its not actually from the patch, and then they say make sure you move it to another area, well theres no where else that i can move the patch without the rsd being there.
