My itching is only on my arms, since 1988. But if I take an pain meds, then I am allergic and it is this awful feather like itching all over, pain is better. As to abdomen, if I get a bad stomach ache or I am on antibiotics then I take a probiotic. It's amazing how great it works. I am constantly tested all the time, blood work slways. I am the only one in my family with these issues. So strange. I hated to have my right knee done and cataracts, but putting off, just so tired of the doctors. Lately some pretty bad ones. I figure nothing is going to kill me, it will just make life miserable, just my luck I will out live everyone.
