Caution for TMJ patients
I have TMJ in my jaw and this sling is so very tight (and I have a small head) that it gives me a headache!  It literally pulls my lower jaw back until my ear hurt.  If I continued to wear it as is I believe it would have reversed all the work of 2 years of wearing a jaw brace.  So I did some modifications on it and added a good 2 inches to the top so it fits much better.
