I have undergone a RCT on my 7th tooth which was successful and did not cause any issue for past 3 months. There was a wisdom tooth in 8th position which my doctor tried to do a RCT but failed. So that 8th one was extracted. I was fine till this time, when the gum healed after extraction of 8th tooth, my 7th tooth started paining and it became impossible to keep the cap on top of the 7th tooth which was placed after rct. So my doctor removed the cap and gave me some antibiotics and painkiller. I completed the course but did not improve my situation. The gum was still swelled and it looked reddish. After that my doctor extracted the 7th tooth as well to make me feel better. Still it did not work, its been 22 days, I have completed all the medication but the gum is still swelled, i have pain in there which is not reducing. Added to that, my lower part of chin is swelled and paining. I am a thyroid patient, I dont have bp or sugar. Attached my whole mouth xray

After completing rct in 4th  6th & 7th no of tooth in my left lower jaws, pain is acute in my 7th no left tooth, doctor had suggested to extract that one. He was extract on 4th Feb 2022, Pain is remaining on. Then he removes the cap of 4th to 6th no of teeth. 6th no teeth was infected. Then he extract 6th no tooth on 4th March 2022. Swelling and pain is going on in my left jawline & my thyroid glands (under my chin) is swelled and painful too. I am helpless, please help me.
