I am 38 years old and started one year ago with tingling in the extemeties and in the scalp.. Symptoms totally went away for several months and started up again about 6 months ago,with tingling sensations all over the body and scalp...Went to neuro and they found bulging disks in lower back but nothing else. Went to dermatologist and is treating me for seborrehhic dermatitis.. I do break out with a rash across my chest and neck for no apparent reason and then it goes away.. I am extremely tired some days and I do turn cold and purple in my fingers and toes... I have had blood tests and my c3 llevels are slightly low but sed rate and c4 are fine.. This is constant goignt o get another neuro opinion.. Does any think this could be lupus???
