Whatever you do avoid any and all pain killers except perhaps aspirin. Opiods are hardon killers for sure.
You could have circulation issues, perhaps heart problems, but yeah, see a doc and don't feel to embarrassed till they say drop em.
The doc might even prescribe something like nitroglycerin which is usually to lower blood pressure and make blood flow more easily. Come to think about it aspirin might help. Aspirin thins blood and is a cheap one you can get anywhere. Just a baby aspirin might do the trick.
Avoid alcohol, weed and coffee too till you get it figured out
