<s>[INST] Hello I was just diagnosed with MRSA. I had a sinus surgery three weeks ago and two teeth removed upper left. I Have a lot of pain in the maxilla  area. I was put on clindamycin 300 mg. Is that an ok antibiotic? I have a lot of pain in the area described. [/INST] Hi. Thanks for the query. Pain after 3 weeks of extraction and sinus surgery is not normal as by now the pain should have reduced in intensity. So my suggestion is to consult an Oral Surgeon and get evaluated and an x-ray of the sinus and extraction site should be done for confirmation. Yes, Clindamycin is appropriate antibiotic and if Infection is still present then you can continue taking the same.Also, you should take painkillers like Ibuprofen for pain relief. If pain is severe higher painkillers like Tramadol or Motorola can help. Hope this helps. Regards. </s>
