I have similar symptoms and no one seems to know what it is. Numbness, tingling, burning sensations over all the body. Symptoms came on after going off of a medication. Subsides somewhat when move or rub areas but not completely. Thyroid not problem, All blood tests came back ok. My Dr. thinks it may be neurological Itches so that can not tell how hard scratchinig and making scabs. Also even the wind blowing over me is hard to handle. Can’t take clothes touching me either. No relief really.
