<s>[INST] Hi, I have a rash that seemed to start with itchy shoulders I thought it was just from being out in the sun, this lasted about a month, then I ended up with a tick bite on my right thigh, not sure how long it was there, the tick was imbedded pretty deep. I was able to get it out but then my rash spread to my forarms and was very itchy. It was a welted rash that got worse when I would go outside in the heat. It ended up spreading to my chest , under my breast , my stomach and on my thighs between my legs. I went to the doc and they ended up treating me for scabbies, and an antibiotic for lymes just in case. I ended up with a horrible reaction to the antibiotic a week later and quick taking it. They also ended up prescribing me a topical antibiotic. The rash now a little over a week later covers my inner forarms, up under my arms pits, my chest and my inner thighs. It is scabby looking now with some of the bumps with deep centers that are black in color. I have some on the sides of my hands that are really deep. I still feel the flushy itchy feeling when I do outside so I am just advoiding it. I am hoping it heals on its own now but I am worried that I dont know what it is. No on else in the family has gotten it and I am married and sleep in the same bed as my husband. I have photos but dont see where I can upload them. [/INST] Hi, It seems that you may be having lichen ultimatum. The cause would be hypersensitive reaction to insects.like ticks. There may be itchy popular eruptions anywhere on the body. Take anti histamines like levocetirizine till, you feel better. If the condition is embarrassing, you may take steroid in tampering dose. Apply combined cream of steroids and antibiotics. Avoid soap bath. Important thing is to be away from insects. For that, you may use insecticide to keep the room insect free. I hope you got my answer. Thanks. </s>
