Hey there, did you ever find out what was puzzling you? I have an electric shock like pain in my gums alongside by back molar on the upper left side. I've seen numerous doctors from dentists, ENT's, periodontist, endodontists, etc…They can't diagnose it. Mine is all the time. It's so annoying and it is painful. Doctors say all looks normal. Mine was felt after taking an Antibiotic (doxycycline) and a muscle relaxer (cyclobenzaprine). I took them on two consecutive nights. I started having my issues shortly after that. I am getting desperate though. Please respond back and let me know what your outcome was. Thank you.
