I would use Deep Relief or Pan Away. You can buy directly at www.youngliving.com
Might be faster to buy thru Amazon, but more expensive. The spouse and I could not live without one or the other of these essential oil blends. Anyway, get one or the other and apply/rub into affected area. Then wrap that area in a heating pad and take a nap. The heat drives the oils into the deeper tissue. Repeat as needed. I get horrible Charlie horses in my legs like debilitatingthis is the only thing that works.
Be careful not to touch your eyes or privates after applying. Yowza.
