I had the nexplanon implanted 4-5 weeks ago and had it removed a week ago because of horrible side effects. I developed a rash on my legs two weeks after the implant that looked like bug bites and now looks like chicken pox. It has spread to back of my arms, forearms and is now spreading to my back and stomach. I went to my dr three times who is now sending me to a dermatologist bc she thinks it s bacterial folliculitis. I m very active and in the water a lot but could this be a reaction to the implant. I never had anything until then.
