After I went to the dentist 4 years ago I was in excruciating pain and thought it was my wisdom teeth but after a week  it finally eased up and now my lower left side on my gums will swell then it will turn in to a hard bump and then it will go away this happens about once a month maybe longer at times. I am pretty sure the dentist scratched my gums which is how this all starte.  So what am iI dealing with?
Hit start with wisdom tooth pain experiences are variable. Most cases come up with excitation pain WRT to the gums covering the wisdom tooth partially, with food debris and infection cumulating over that area. This may get eased off if the gums are cleaned but may reoccur after a certain time gap. The treatment modality in such a case is either extraction of the tooth involved or operculectomy(removal of the gum tissue covering the tooth partially) if it has erupted some bit more.a minor scratch from your doctor cannot cause a huge bump also the same condition that you have mentioned had arisen in your lower gum as well. I advice you to go to a dentist as he will be the best understanding the treatment need clinically.trust your doctor. Take care.
