<s>[INST] I had a osteroscan on oct.22 and now i have a severe rectal rash, and skin rash on hips legs and arms itching. The rectal rash seems to be spreading, and has had clear liquid pouring out if. I have had diareha for years, (10)but the rash  started after the ostero scan. They said I have a pheochromo on my right lower lung, but gave me the ostero scan to look for carsanoid, which was negative. [/INST] Hi, I can understand your concern for rectal rash, itchy skin rash on hips, legs, arms which ooze out pus. Let me first reassure you that the kind of rash you are mentioning can not be by any diagnostic technique. SO do not correlate your condition with any type of diagnostic aid. After reading your query it appears to be due to fungal infection with secondary infection. Fungal infection of the skin is quite common in this hot weather and the further spread of infection to nearby of other parts. To prevent the further spread maintain good hygiene by taking two times bath, wearing cotton clothes and change of clothes two times. You can also use nay good medicated antiperspirant powder. Stay away from hot and humid climate. You can use clotrimazole cream or terminating cream locally over the affected areas. Do not try to scratch the area further as can cause secondary infection. You can take antihistamine like loratadine for two times a day. If there is any pus then you can take a course of antibiotic under medical supervision. The best would be to consult a dermatologist and take the best guidance. Take care. </s>
