What conditions might be associated with: intense internal itching primarily on palms of hands and bottom of feet, and then spreading to body with no visible rash (only one small blister on back) and ending in some small bruising in areas of body from no apparent reason?? Cold compresses seem to have offered the only relief. The itching has started to subside some after approximately 72 hours. No previously diagnosed conditions, allergies or medications. Have had chickenpox twice and shingles once previously, not sure if any connection.
