The pain in the calf for several days after a leg cramp is often a sign that the leg cramp is serious. The main reasons for long-term pain are as follows: first, the leg cramps are not handled in a timely manner, resulting in continuous muscle spasms in the legs, and may be persistent and aggravated. This will lead to strains in the muscles and tendons of the leg, and in serious cases, even tears, which will lead to persistent pain. Secondly, it may be due to intermittent cramps after the initial cramp attack, or the muscles in the calf are constantly tense, which may lead to a large amount of lactic acid deposition in the muscles and continuous pain in the calf area. For this symptom, it is recommended that the patient can take the following treatment: First, in the near future, pay attention to the warmth of the calf area, and pay attention to rest, do not strenuous activity. Second, the patient can go to the acupuncture and massage department of the Chinese hospital to do acupuncture, Tuina, cupping and other physical therapy for this. Third, the patient can take oral non-steroidal drugs to relieve pain, such as ibuprofen, loxoprofen and so on. Fourth, if the pain persists without relief, then the patient needs to visit an orthopedic clinic to clarify whether there is any related injury.
