question: My sister just called me. She told me about the swelling in her mouth and tongue and that she had a fever blister on her lip. I told her it was part of the herp 1 virus, most people have it, kids get it from adults, anyway, Im an RN, then she began saying her hands were swollen, she is on a beta-blocker, and on a water pill. Then she said about two months ago her neck swelled on both sides to the size of her fists, I asked why she didnt get checked, that she could be having some dangerous circulation issues...just curious what do you think?
