A year and a half ago I bought some Retin A on line for a wrinkle on my forhead, used it maybe 6 times in 2 weeks and my skin was like a wet sponge. If I touched it, it indented and stayed and the skin peeled off my nose completely. I don't know if it was that or an ingrown hair on my arm, but I developed a staph inffection of the skin which was extremely painful. My gland swelled up on the side of my face, I had repulsive looking sores on my arms and a few holes in my face. My doctor said to stop the retin A, gave me an ointment and antibiotics for a month. My arms stung like shards of glass was inside tearing its way out and I googled it. It led me to a site about people who had things, bugs living under their skin. I PANICKED!!! That night I hallucinated that "Bugs" were flying around me and into my skin and I couldn't pull them out. I screamed for my Dad and he came in and said I had tweezers, scissors, and clippers tearing at my skin saying help me get the bugs out and nothing was there. I even had him call 911 and went to the ER who said I had a parasite w/o even an exam or knowing I had Staph. Never told my doctor, too embarassed and realizing it was in my mind. My question is, was it anxiety/panic/depression that caused it? Or was it the toxins from the severe staph ( almost MRSA ) infection that caused it? I live in fear of having another one even after 1 1/2 years. Am I crazy??? I remember the paramedics being worried about my blood pressure being through the roof. I was alert but confused and now have significant scars on my arms as a constant reminder.
