Are red horseshoe shaped rash on arms and diarrhea related?
Patient: I have just noticed a red horseshoe shaped rash on the insides of both my arms, which became more pronounced after having a bath.  They are itchy, but not crusty or oozing any fluid.  They seem to appear worse when I am warm and almost disappear when I am cold.  I have also had diarrhoea for the last 2 days don't know if it is connected? Doctor: HIWell come to HCMI really appreciate your concern, this could be hypersensitivity and this could be due to some allergens some time this may be associated with abdominal manifestation, diarrhea and nausea, condition is more or less is self limiting, wait for couple of days to come around take care for hydration, if this does not come then you can try antihistamine "Tab Levocetirizine 10 mg three times in day, for diarrhea just do nothing, hope this information helps, take care.
