This is a 'common' thing with TBD's. I personally have it all the time, as many of us here on the forum.
The only thing that gives me relief for 1 to 2 weeks is going to a good osteopath, or going for fascia therapy (mine does both). He takes away the tension. It comes back, but at least I get some relief (never disappears completely, but the 'unbearable' feeling goes away).
Sorry, what is TBDs?
When I had this before, I couldn't hold my head up myself and had sharp pains in and behind the eyes. That's happening again...I have sharp pains in/behind my right eye and my neck is very painful and weak and stiff. My hearing seems to be affected also. So I guess this is just a common thing to expect?
