[|Human|] Hi Dr Prasad. This morning, after my shower, I noticed a red rash on my legs around my groin (no rash on my testicles or penis). I also had a rectangular patch of rash just below my armpits on the upper arms. I took 2 tsp benedryl and went to work. All seemed fine, but on the way home the itching came back. The rash under my arms has now spread to my chest and around my nipple region. I have a more pronounced rash on upper legs, and behind the knees. Small rash developing at the waist line. Basically wherever there was rubbing with clothes or watchband. I have not changed soaps. I have not changed laundry detergent. I DID cut down some branches from my tree and there was sawdust everywhere (not on my groin though). I also noticed a lot of some sort of fecal matter on top of the roof where I was sawing branches.
[|AI|]  Hello. Thank you for using Ask doctor service. I have gone reviewed your query and here is my advice. You seem to be having Hives. Hives present as itchy welts and redness/flare. They can be localized or they may be widespread. Common causes include allergic reaction to food, food preservatives, infection, Chat Doctor.  Consuming alcohol may also cause Hives. I suggest you to take an oral antihistamine e.g. cetrizine10mg tablet once a day for a few days. You may use a soothing lotion e.g. calamine lotion for to calm down the rashes. Hope I have answered your Quertle me know if you need any further assistance on this.
