My father has developed a rash/allergy-like skin issue on his leg. I’m attaching a photo for reference. Could you please have a look and let me know what it could be? Does it look more like an insect bite, an allergic reaction, or something else?
For history/info: he recently changed his
diabetes and BP medications. He is also currently taking antibiotics for an intestinal infection, including Rifagut (rifaximin) and some other medicines. He has undergone CABG surgery in 2018.
Could any of these medicines be causing the rash? Please advise if he needs any treatment or if we should get it examined in person. Thank you.
