Sciatica is a syndrome characterized by radiating pain originating in the lower back and extending through the buttocks, back of the thigh, outer side of the calf, and outer side of the foot. It particularly affects those who have experienced external exposure to cold, dampness, or injury from local strains or overexertion, leading to stagnation of Qi and blood stasis type of sciatic pain. Cupping therapy has been shown to be effective, meaning it can alleviate some of the clinical symptoms of sciatica to a certain extent. For example, cupping therapy for cold-dampness type can lighten the local cold and dampness, expel wind and open the channels, and thereby relieve pain. If the condition is due to Qi stagnation and blood stasis, blood-letting cupping can be used to promote the circulation of Qi and blood, remove stasis, regenerate new blood, and alleviate joint pain.
