I have raised, red, itchy, painful welts on my arms & legs, but no where else. I have been this way for the last 13 days. I have tried Sitz-baths with cold water and Epsom salt, Benadryl pills, creams, medicated anti-itch creams. I finally went to the ER because I couldn't the itching any more. I have had several people tell me what they it is that I've got. 1st Doctor at the emergency room told me that they look like bed bug bites. 2nd Doctor told that I had strep. My Mom thinks its: Shingles, my sister thinks they are spider bites, my neighbor thinks its MRSA. I don't know what it is or how I got it. Any and all suggestions are appreciated. I have never felt some miserable in all my life. If anyone has had this problem or have any advice please share. Thank you for your time & patience.
