Hi, For about the past week I have been experiencing a burning sensation on the tops of my feet. It is not sunburn. They are not swollen. I take Tekturna, Hydrochlorothiazide, lorazepam, levothyroxine, and for the past month have been taking phentermine to help with weight loss (it's working). I take a multivitamin and D3. No herbal supplements. About every other day, I take a calcium, magnesium, & zinc tablet. I don't feel sick or have pain or any other symptoms that I am aware of.
