How many days ibprufen is harmful?

I am having lower jaw pain and swelling for one and a half months. had sinus infection. Dr gave antibiotics and indomethacin 50mg NSAIDs. took it for a week twice a day. nothing helps. had the same level of pain and swelling. took ibuprofen for few days along with paracetamol. didn't help. went to dentist and he prescribed ibprufen 800 and muscle relaxers. took for 4 days. dentist told me to extract the upper wisdom tooth and did that last Thursday. so after the extraction,I was given antibiotics and ibprufen 800 two times a day for 8 days. I feel like I am taking lots of ibprufen and antibiotics. does NSAIDs and antibiotics harmful? I would have taken NSAIDs for a total of around 20 days. is it harmful? does it harm kidney or stomach? should I stop taking it? I still have the same jaw pain under the ear and swelling. how long is considered long term usage for NSAIDS? please help.
