The reason for sciatic nerve pain caused by too frequent sex is the continuous contraction of the gluteal muscles during sex and the twisting of the lower limbs, which can easily lead to acute sprain of the pear-shaped muscle. The pain can spread to the posterior thigh and posterior lateral calf, and in severe cases, the pain is severe, and coughing or sneezing can trigger the pain to increase. Treatment methods include local massage, massage and ultrashort wave therapy, which can promote the blood circulation of the pear-shaped muscle, release the spasm of the pear-shaped muscle and relieve the local pain symptoms.
