Well I am not sure I should be saying this. We have been treating TMJ disorders for many years now but we do not use Mulligan's technique which is more of a physiotherapy procedure, we use splints which you will have wear, which is more or less same technique and is non surgical. I have done an extensive study of TMJ disorders in North India and you will be amused to know that I also suffer from TMJ clicking.

Since you are  having this problem from more than a year..so it's better you should go to dr ajai.rai sir hod of oral and maxillofacial surgery Aiims new delhi

You can search online for a good oral surgeon in your area who specialises in TMJ problems
