I tried taking some more benadryl and and lathered myself in hydrocortisone cream. I stopped itching for about 2 hours. Now its back with a vengeance. I lathered on another coat but its not working anymore. I itch so bad, I could cry. And I think its getting worse. I think I will call my doctor in the morning. Doesn't look like I'll be falling asleep anytime soon.
