About 2 to 3 weeks ago i was cutting some pants of a tree because it just took away from the tree but i later found out that it was poison ivy. i dont think i had ever fallin i contact with poison ivy. now well a few days ago i started itching on my arm but i thought it was a mosquito bite. so i was scratching it without thinking much of it and now its starting to have more and more little blisters where i scrached. can anyone help me with what i can do to get rid of it without going to the doctor.
