I was either sitting in front of the computer or walking around with high intensity, and as a result, my lower back was constantly hurting. I once bought some pain relievers, but they didn't work. One time, Tongrentang's wormwood lumbar vertebra paste was promoted on Yamibuy.com. I bought a pack with the mentality of trying it out. I didn't expect it to work. I only posted it once, and my old waist has been pain free for four days. When I opened the package, the thick herbal fragrance wafted out. After half an hour to an hour after the lumbar patch was applied, the place where the plaster was applied felt hot, which lasted for a whole night, and the next day Get up with no back pain! thats just splendid!
