I m a 79 year old man, wintering in Fl. Have very itchy skin, raised bumps/ pimples , rashes under arms, pimples on colar bone, tried one week of MethylPrednisolone , no relief. Have had for about four weeks. Have use antihistamines, no relief. Emergency room Dr. gave me a Permthrin Cream to use in case I have Scabies , but I was afraid to use, because I didn t know what the side effects would be.
Hi welcome to Chat Doctor forum.  Thanks for calling Chat Doctor. Forum.  You are having itchy skin, raised bumps, pimples, rash under arms, pimples on collar bone. You have used prednisolone, antihistamines, and permethrin cream, but in vain. You have allergy that is right, but there is associated super infection.  When ever there is infection you are expected to use antibiotics along with medicines for controlling allergy. So I advise you to consult a dermatologist for diagnosis and treatment. If you have any doubts you can approach Chat Doctor.  Wishing for a quick recovery.  Best regards.
