For the past few months I have been experiencing unbearable tingling sensations in my legs, ONLY when my body gets hot. The tingly feeling has now began to spread to my knees and lower thighs. I will feel small tingles in random spots on my arm and stomach. I can be cooking or washing dishes or entering a hot car and the second my body gets flushed with heat, the tingles start. Only way to SOMEWHAT soothe the irritation is to rub my legs. However, if I enter a cool setting it immediately stops. I have read some one else describing the same thing. He has been to the doctor and had many tests ran, all coming back negative and saying that he was healthy. They do not know what is wrong. Whatever this is, it s really starting to ruin my life. I can t even exercise or do any vigorous activity for that matter without being highly irritated. Please help.
