<s>[INST] I have been spitting up brown yellow phlegm for about a year and a half, I dont smoke im 22 and recently ive been having dull pains in my left arm, The dullness is maybe a inch long and it comes and goes, also when i eat alot both my lower sides by the kidney area has a dull feeling but goes away when i dont eat much, my right arm never feels weird, I also eat out "junk food" every day. Im not over weight. These have been going on for about a month on and off every day or so. I dont have health insurance and need to know if this is a doctor visit asap. please help me out in what this could be.. i also have maybe 2-3 small red dots on left are called something like Picate but my mom also has those [/INST] Hi, thanks for post, phlegm for a year could be some serious disease, especially if fever, decay, loss of weight are present; bronchitis, interstitial lung disease, tuberculosis, pneumonia, bronchiectasis, are examples of illnesses which cause long duration phlegm, with respect to pain, it is common in lung diseases pain with similar characteristics, but it is something to investigate could be necessary chest x-ray, tomography or magnetic resonance, blood tests, to begin, anyway you have a disease to study, because every illness has a different treatment, and I recommend visiting your physician, he'll examine you and tell if you have secretions or any anomaly in medical physical exam. </s>
