<s>[INST] I have had a rash for 4 months after th doc. prescribed cortisone nasal spry (which did nothing). after getting flu from my grand-daughter.He gave me Cyrrhus to help the rash and the congestion - it did not work and now the rash is as before and looks really bad after a wrm bath!! [/INST] hello, thanks for ur query, rash for 4 months could be due to urticaria, u need to see Dermatalogist for farther rx as some skin conditions can be diagnosed by naked eye examination. all d best. take care. </s>
