After sitting in the last class for a day, I often feel pain in my lumbar muscles. When it's light, massage or hot compress will relieve it for a while. I have to take medicine when the pain is severe. I used to take vodka tablets. I don't know if it's because of bad stomach or other reasons. I took it several times and occasionally vomited, but I got better after stopping using it. Later, a friend introduced me to Yingtaiqing diclofenac sodium sustained-release capsule, saying that it would have no adverse reaction, and it would have an effect in about an hour, with quick pain relief and long action time. There is also an Yingtaiqing diclofenac sodium gel, which can be applied to the painful part for five minutes to relieve the pain. The two drugs can be used alone, but the combined application has better analgesic effect. Anyway, I use it in combination, and the effect is really good, which is worth recommending.
