Be very careful with Tramadol. It can be addicting and can be very hard to get off as itnhas an anti-depressant component to it as well as a pain killing component. Ask your doctor about CoQ10. It's an all-natural supplement and my daughter has had great luck with this. It does take a few weeks ro kick in.
This is the IMITREX injection pen?
I have no anecdotal information to share, and with questions like this, you really should talk with your doctor. The medication works by inducing vaso-constriction, and perhaps you're experiencing more vasospasm than you should. As to why alcohol causes the same reaction is a mystery as alcohol normally causes the opposite response -- vaso-dilation.
Perhaps you need a lower dose or a different medication -- please consult your doctor.
