TMJ Pain and deep bite. Pls help!

I am suffering from TMJ pain since 3 years. I first consulted my dentist in 2013. Both my upper and lower pairs of teeth were misaligned . Now , through wearing braces upper teeth have been corrected ( still wearing braces ), but the doctor was very conservative in his approach and finally he decided to give a bite-plate to wear for lower teeth , so that my lower jaw will remodel itself. That reduced pain for a certain period of time , and the pain started again. So, I consulted another renowned orthodontist a year ago , whose treatment plan is to first extract two pairs of teeth( for faster progress ). Next , both my lower and upper teeth were tied with braces . Later, I was asked to wear Trainer ( for TMJ pain) during overnight and atleast one hour during day time.I am wearing that since 6 months . My deep bite has changed , and my pain gradually reduced.Now again it has come back, and this time more severely. I am not able to talk and chew the food as it pains immensly.pls help
