<s>[INST] Eight years ago, I spent several months in the hospital for an aortic anyeurism & a dissection. I am on Medicare, and have been quite pleased with the level of care I have received. Currently, I have a bad tooth that began to develop an abscess, resulting in swelling of my lower jaw, fever, and pain.My ex-wife had a prescription of azithromycin,500mg, on a 3-pill regemin. I started this past Friday & finished today. The swelling has subsided, along with the pain.I had planned to contact my internal medicine doctor tomorrow to find out if Medicare can help me. In the meantime, Ive Googled & Binged for information, and what Im discovering is Im pretty much out of luck (no dental help from Medicare). Any suggestions/ideas that I might share w/ my Doctor tomorrow? [/INST] Thanks for using Chat Doctor. Read your query. The signs and symptoms you have mentioned suggests acute abscess in relation to the decayed tooth, the abscess being subsided due to the use of azithromycin.(Though antibiotic should be avoided over the counter and taken only after the doctor prescribed for you.) I would advise you to visit your dentist and get a radiograph done as to evaluate the tooth which is involved. Go ahead with the needed treatment of root canal. Avoid applying hot bag externally. Hope this was useful. Thanks and regards. </s>
