What is it

[Dominiquelarge]

I keep getting muscle cramps on my left leg, i exercised and i felt no pain, it doesnt hurt to walk either. They are normally on my shin and ankle. It goes away when i massage it

Curious b/c I get some in my hamstring/calf (sporadic but recurring). Mine have gone on for yrs so I have lost interest now :).

Its being going on for a while now and i would like to know what is it and if its going away or if its dangerous
