Do you have any itching ,redness, swelling of the affected portions of the body? Is the itching worse during any part of day or night. The rash need not necessarily be due to the TB test you have undergone. Homeopathic Medicine has excellent remedies like Apis mel, Rhus tox, Natrum mur, Sepia etc. to alleviate the hives and prevent further episodes too.
