Has traptox helped anyone who deals with pressure behind eyes/cervogenic headaches

I deal with a lot of facial pain and a feeling of pressure behind my eyes. I have gotten MRI, CT scan, etc and there is nothing they can see. I think most of my pain is referral pain and comes from my shoulders and neck. Has anyone here tried trap tox? I'm scared because I don't want to make my situation worse. Long term I need to do vestibular rehab, and posture correction but short term this pressure feeling behind my eyes and the constant feeling of someone sitting on my shoulder is really taking it's toll on me. Traditional nerve blocks are not working on me as well
