My child is 3 n 1/2 yr. and he is suffering from toothache at left upper molar. can you suggest instant relief remedy

I had a ongoing RCT of my molar started on (28th-july)first sitting, (29th-july)second sitting,(4th-aug)third sitting because i am only able to get time on weekends. But after my third sitting the pain in the molar and ita surroundings become intolerable so i again consult the doctor and he removed the temporary filling and inserted cotton and asked me that it will be fine now, but even after that the pain is still very bad. I do not understand that is there something wrongly done by the doctor or something else happned. I searched internet and found several possible issue like missed canal etc. Please suggest me what to do, should i consult any other doctors or it is normal or not.
