There are also meds like florinef or midodrine increase BP. You need to be tested to see what is going on before being treated.

The other treatment for vasospasms (besides nitro) is as I mentioned before...calcium channel blockers. They can drop BP a little, but spasms can sometimes be controlled with just small doses.

Your doctor needs to be addressing all of this...even the blood vessel issues...I certainly hope you've brought it to his/her attention and that he's seen what you're describing.
