Tapping and pressing pain after RCT.

Plz take a look at my x rays and let me know if my RCT is done correctly or not as i still feel tapping pain and discomfort with burning mouth palate and burning tongue even after a month of my RCT...let me tell u there was no infection in my teeth and these were my healthy overly trimmed teeth and doc said bcoz of pulp expose, RCT needs to be done..he does not have x ray facility in in his clinic and he did not approve the IOPA x ray that took took to him..anyways after OPG he removed my previous cap(had put on and removed twice bcoz of pain) did the rct in that very sitting...all the procedure done in about 40 mins.. but i still feel tapping pain, also my premolar structure is lost a lot...so does it need any build up before putting on the cap?what can be done to rectify the mistake, if any in this RCT?can it pose any problem in future if i go for cap incase the pain subsides with lil more time?plz guide me as i am in great stress from last 6 months, have already lost too many teeth.
