I've just tried cupping. After severe back pain and not being able to walk for two days I have no longer severe pain in the nerve but even after many days my muscles in the lower back and my glutes ate very tight and with spasms sometimes if I get up fast.
Buying the cupping kit on ebay is cheap. I bought the one that the pump hasn't got a long plastic tube. I put some coconut oil on my lower back for better suction. I also put some coconut oil on the joints betweenthe pump the and the cups in order to enter and eject the cups easily. I definetly felt my muscles and the area being pulled off and some relaxation and a pleasant feeling afterwards but I need more testing and repeating the methods more days. I cupped for 10 minutes. If suctions leaves some marks on the skin they will dissapear in 2-3 days.
