I have had the same issue with my left leg, I also find that heat works well that I create with my hands.
The pain completely goes away when I rub cold pressed hemp seed oil on while creating a bit of friction from the rubbing that creates some heat, if I stop doing this for a month, the pain comes back.
Leg cramps and pain makes it very hard to get some sleep, sleeping well these days by not missing to many days from rubbing the oil on, also great for the shoulders back hips stomach mussels and dry skin.
As a small farmer I also get small hernias from over doing it, the hemp oil helps to get rid of the pain and reduce them.
My spirituality practice is also a big factor in mostly feeling well these days.
