Posion ivy, oak, or sumac?|
 I have posion ivy, posion oak or posion sumac. I am not sure which I have. 
 It looks like a rash with lots of bumps on it. But it only comes it groups. Like an odd shapped circle. Its not a complete circle though. Its red and itches. I have it on my arms and hands. 
 Can anyone tell me what you think it could be? 
 Your opoinons will be very much apreciated.
 Does anyone have any idea what I could have? |
