so much pain now

got ripped off by a dentist so I complained, since then I have found it hard to get dental care. but I needed it. got an abscess, that didnt heal so had the tooth out then got dry socket, its week 3 post tooth extraction. just prior to that I had a filling that wasnt done very well. during that filling the dentist damaged my jaw. this tooth I am told by another dentist needs either a filling or root canal Its agony , which I cant afford. ( ive never had this sort of thing happen before even with abscess etc which ive gone through before. Im doped on pain killers. the jaw joints are painful to put it mildly , the ears feel full and the buzzing is crazy.
