I followed my doctor's suggestion, and
did start taking
an antihistamine, Zyrtec
, 10 mg once a day. It worked. I took it for two days, and then stopped. After about 3 days, the itching returned, so I took only 5 mg (cut the pill in half), and it again worked. I have essentially continued this pattern ever since. About every three days, (sometimes two days, sometimes four), I take a 5 mg dose, and the itching stops.
