Wierd Uneplained Scratches

Hi,
For the past few months I have been getting wierd, unexplained scratches on my upper torso (my sholders, neck and chest just above my breasts). I am 21, I have no pets, dont scratch much (well at least not in these areas),  I have no medical history for any disorder except asthmaand PCOS, its not scabies or any misquito, tick or worm, and only happens during the day when I am awake. The scratches usually come up in threes but some times one or two about 2 inches long, which then turns into a welt (like after a cat scratches you and the sides of the scratch flair up), the scratches are only there for a few days and then just vanish occasionally after a couple of hours. I litterally do nothing that could even remotly cause the scratches (i use my hands all day or am on my computer). My doctor has no idea what they could be (mind you my doctor i honestly wonder how he is able to practice). Can anyone help me.

Hello,
Such a rash that is itchy and which appears and disappears is due to urticarial patch. You can take some OTC oral antihistamine medications like Benadryl or Claritin and see if it helps.

For mild-moderate symptoms a weak steroid may be used (e.g. hydrocortisone as dermacort), whilst more severe cases require a higher-potency steroid (e.g. clobetasol propionate, fluocinonide).But they are available under prescription and should be taken only after consulting a dermatologist.

It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided. For exact diagnosis, you are requested to consult your doctor. I sincerely hope that helps. Take care.
