<s>[INST] Hi, I'm 34, female, slim; no health issues other than asthma. About a month ago I noticed some discolouration on my stomach. It has a sort of marbled look and stretches a few inches around my belly button. I'm very pale skinned but this discolouration is a pale brown in appearance. I've also had a niggling dull pain to the left and below my belly button but it's not a bad pain. It would be great to know what you think. [/INST] Are you taking any medicines for asthma or ar you taking any medicine in between for other problems some medicines used in asthma or other diseases cause this li8ke paracetaol,disprin aspirin brufen and vitamins and dietry suppliments check for these </s>
