Hmm in not too sure @Joe Cuber I think mine maybe due to jaw/neck issues as its only when I'm lying down or on my side. Upright and it fades into a nothingness and I'm left with my normal T which I can handle better now . Maybe yet another trip to the Dr is in order, seriously they must be sick of seeing me by now lol.
@Joe Cuber definitely gonna see if I have anything like that. Waking up when you are already tired is sure a pain in the arse!! Have you been given any at home exercises to do?
