I get red dots, or worse rather easily too. Usually from things that increase the internal pressure (relative internal pressure), so pumping, clamping or jelquing.
They range from tiny to big blotches depending on the amount of pressure. I take them as a good indicator of when to back off. I think a few the size of a pin head are fine, more than that…too much pressure!
As you know, these are busted blood vessels, and its you bodys way of saying that you are at your sensible limits…don’t go farther.
I find if I work up slowly for a few weeks, I can push the pressure higher and not increase them. You give your bloodvessels a chance to adapt.
I know that quercitin also helps with the vessel wall strength, especially it you combine it with vitamin C.
I usually don’t get them stretching, unless I turn the stretch into a jelque (trap blood and force expansion), so see if you are creating too much pressure with trapped blood when you stretch.
I think you should let them heal completely before restarting, then gradually work up. Try and avoid creating them, I don’t think its a good thing to have. These red dots are different from discoloration, they are broken blood vessels, discoloration is the deposition of hemosiderin, which is iron from blood that gets trapped in the tissues.
I don’t thing either one is good, but discoloration is ok with some guys, but I think broken blood vessels aren’t something you want to keep doing.
Good luck.
