Your description does not suggest any particular diagnosis. Scabies is an outside possibility, but this is by no means certain. It might be worthwhile to ask your general physician for a prescription for a scabies overnight treatment--even if it doesn't work, that information will be useful to your dermatologist. And of course if you do clear up in a few days, that will both prove the diagnosis and solve the problem.
Otherwise, I think you will need to wait on the dermatologist's examination and opinion. A skin biopsy may be useful. Meantime, take the anti-itch medications, as they are providing at least temporary relief.
