I have high BP and am on medication for it but it's due to no other reason than the fact that I've gained so much weight and a family history of high BP, high cholesterol, and heart disease. And the only way I could blame the BP on anything to do with my pain,etc. is the fact that as soon as I started taking Neurontin I seemed to gain about 35 lbs. overnight. Otherwise, I don't feel it has anything to do with my TOS or any of the other problems I'm dealing with.
