I occasionally get random cramps in weird parts of my body. Parts that I can't seem to find a way to stretch. The only thing I can do is try to massage it or use my vibrating massage ball against it.
However, it only works for a short time (like a few seconds) before the cramp comes back again. For example, I am having a cramp in a place on my inner thigh which is really near my crotch after running(somewhere around here):
I've tried all of the above, but it still won't go away. Sometimes I also get random cramps in parts of my arm or neck that I can't stretch, so I just have to deal with the pain until it goes away.
Are there any other methods to relieving these types of cramps in awkward places? And is there any way of preventing them from happening in the first place since they can't be stretched?
