The vessel just blew up.You`ve got very frail vessels.You`d need to take something to strengthen your vessels, smth like horse chestnut or similar.
The most innocent injury, ( yours may be more than that) can turn nagging and then chronic. Years can pass then " son of a bitch, there it is again" The extra intensity is not worth it. Absolutely amazing to me that you state you have no experience with injury due to exercize. Any, any discomfort during workout should end the workout for evaluation for at least a day before continuing. Just an example..... The athelete who toughs it out with a sprained ankle is always done for a few weeks with the broken blood vessels etc... once the event/game is done. Good luck and care for the future.
" easy bruising might be caused by consuming excessive amounts of fish oil, ginger, garlic or ginkgo biloba, all of which can thin the blood." Well, are you taking those? I actually eat garlic and fish oil quite a lot... ---------------------- Apparently, there are 3 different kind of bruises: http://www.livestrong.com/article/19279-causes-bruising-easily/
Looks like a fairly bad case of kurtosis to me. Happened to a friend of mine. He started to recover fairly well for about two weeks but then his private parts fell off.
That must have been some fierce intensity with crazy wide strides. Can't imagine how else you would have pulled or slightly torn your muscle. Hope you get better soon. Have you ever considered doing HIIT with bodyweight squats, perhaps for a bit of variety? It's my exercise of choice for intervals. I mentioned it elsewhere in the past, where you do X reps at a brisk pace, followed by Y reps at max speed and then repeat for a number of intervals. Should you ever decide to try it, you may wish to not go below 90 degrees or lock out at the top for the speed portion because doing so slows you down. If you ever do decide to give it a try, please let me know how it goes.
I haven't done bodyweight squats but I recently did HIIT training with burpees, which is combination of a pushup and a bodyweight jump. I actually liked that workout quite a bit.
It's getting better but it's really slow. If I sit at my desk too long, it will start bothering me so I will move to the sofa or recliner to prop it up straight. I did a brief upper body + calves weight training workout earlier this week just to keep things flowing if you know what I mean. I'll probably do the same thing this afternoon.
