Hello from JA
This is not a side effect of sumatryptan
It has not even been reported after market
But difficulty with erections, although not a side effect, has been reported.
Any side effect could happen in a given individual.
So if you don't take the med and don't have erections as you are describing, this would be the test.
Unwanted erections can be normal in younger men, so I am not sure you have an abnormality....discussing with your doctor will clarify.
Let me know if you have further questions, details or need clarification, just use reply.......
