I have lower jaw pain and swelling for one and a half months. Under the ear where the jaw ends. It started after I chewed more than usual one day. Soft food item only. Next day jaw pain and swelling started. Had sinus infection, so thought it's because of that. But sinus cleared up with antibiotics. But jaw pain and swelling still there. Didn't reduce. Went to dentist and they said I might have crack in lower first molar and that is causing the pain, swelling. Also said might be from my upper wisdom tooth. So told me to remove that. I did that 4 days back. I still have the same lower jaw pain and swelling.it hurts to touch under the ear. Hurts while opening mouth wider and while closing mouth too. It hurts exactly in the lower jaw end under the ear. Why it's hurt to touch? What is the reason? What is the treatment for this? Constant pain day and night for past one and a half months. Started third week of may.still same level of swelling and pain. Taking ibuprofen and amoxicillin.help.
