weight 260....female....47 yrs old.....started BP pills 4 months ago, and since have had torso hives (chicken pox style) just before and during menstrual period. 1st month was on back-mid drif right side, 2nd month moved to left, third was in the center and not as bad.This month the hives have spread out and cover my back, a few on the stomach, hips, buttocks and upper arms. Also, glands in both arm pits are swollen and red, hard to the touch, pain level in arm pits like over-worked muscle.
