Hi, my girlfriend is experiencing some form of a burning sensation not directly on her skin but on the inside a burning sensation similar to burning yourself with an iron. No swelling and no pigmentation just that painful burning sensation. This mostly occurs on her feet and sometimes hands, it becomes better when I massage her or when she takes a cold shower as well as pain killers but all those are temporary solutions. Don`t know if this will help but her blood type is o, shes not diabetic and has no allergies. This thing comes whenever with no warning so we cannot really point out if it is caused by something she does or eat or does not do. We would appreciate your help as our dr`s in south africa have no clue as to what it is.
