Sounds as though your sciatic nerve is acting up. I would suggest an indication. Indicas are great muscle relaxers, also serve as a great pain killer.
So sorry to hear about your muscle spasms. I play a lot of golf so i certainly know about =back pain and sciatic nerves! I have had similar symptons to yours for a while and the cream by Mary’s Medicinals called Muscle Freeze – CBD Lotion has worked great for me!
