Calf pain when running

[nameuser]

Usually for cardiovascular exercise I do swimming. The reason for this is because whenever I try to run my calf muscles tighten up and go numb. It's quite painful to continue running, and when I stop after running a few miles it turns into a sharp pain for several seconds.
Due to this, I can't run more than a few miles, not because of exhaustion but because of calf muscle pain.

My calf muscles feel fine after an hour of resting.

I do alot of anaerobic exercise on my calf muscles. I was wondering if the reason for this was because of using weights to build up my calfs? If so, I'll have to stop training them.

i think the pain will gradually fade away if keep on running one day after another...just hang on there, don't give up, one step at time till u reached that mile!!

my friend had the same thing and he was told it was compartment syndrome.
