[|Human|] I have a cold now but have had dry mouth in the winter months. a few times per week I may see streaks of blood in my spit, it goes away after a hour or so
[|AI|]  Hello. Welcome to Chat Doctor. Spitting thin streaks of blood during or immediately after recovery from sore throat infection is a common finding and is due to increased blood flow in the pharynx during inflammation. So, it is not something to be worried about.  You can have soothing effect or relief by having sips of warm water instead of normal temperature water whenever you are thirsty. Coughing out or spitting blood in your case may be a cause of worry if you also have otherwise cough with sputum production, or have other symptoms (loss of weight or loss of appetite)suggestive of tuberculosis. In any case if this finding of cough with blood streaking persists beyond sore throat, you must have X-ray and visit a chest specialist. Take care
