this am I woke to the middle of my arms itching and red; 1/2 hr. later it all seemed to go away, occasionally being a little itchy. this pm I am itching up a storm. arms, legs, belly, back are all itching without giving up a minute. I have tried vinegar cortisone 10, calamine lotion, nothing is stopping this itch and red blotchiness. seems as if its being spread by my itching. should I go to the er or is there something I can do
