What happened to the lower back pain the day after having sex

The second day after sexual intercourse, lower back pain may be related to factors such as muscle strain, pelvic congestion, urinary system infection, lumbar spine lesions, kidney deficiency, etc. It can be relieved through methods such as hot compress rest, anti infection treatment, and traditional Chinese medicine conditioning.

1. Muscle strain

Continuous tension and contraction of the waist and back muscles during sexual activity may lead to lactic acid accumulation and cause soreness. This condition usually manifests as stiffness in the muscles on both sides of the waist and increased pain during movement. It is recommended to rest in bed for 24-48 hours and apply hot compress at around 40 ℃. External application of Huoxue Zhitong ointment can be used. Avoid repetitive intense exercise in the short term.

2. Pelvic congestion

Prolonged pelvic congestion caused by sexual arousal may compress the lumbar sacral nerves, leading to a common feeling of lower back heaviness and discomfort in the perineum. You can use 30g of Ai Ye decoction water to fumigate the lumbar and sacral regions, or follow the doctor's advice to take Xuefu Zhuyu oral liquid. It is recommended to adopt a knee chest position for 15 minutes to promote blood reflux.

3. Urinary system infection

Unclean sexual behavior may lead to acute cystitis or prostatitis, with typical symptoms of lower back pain combined with frequent urination and urgency. If the diagnosis needs to be confirmed by routine urine test, traditional Chinese patent medicines and simple preparations such as Sanjin Tablets, Relinqing Granules, or antibiotics such as Levofloxacin Tablets can be used according to the doctor's advice. During the treatment period, drink no less than 2000 milliliters of water per day.

4. Lumbar spine lesions

Patients with pre-existing lumbar disc herniation are prone to symptoms during improper sexual activity, and pain can radiate to the buttocks. Diagnosis requires lumbar CT scan. In the acute phase, it is recommended to lie on a hard bed and receive traction treatment. Chronic phase can be treated with Yaotongning capsules or with Feiyan style lumbar and back muscle exercises.

5. Kidney deficiency

Traditional Chinese medicine believes that excessive sexual activity can damage the essence of the kidneys, manifested as weakness and fatigue in the waist and knees. Patients with kidney yang deficiency can choose Right Return Pill, while those with kidney yin deficiency can use Left Return Pill. Massage the Yongquan acupoint in daily life and consume kidney tonifying ingredients such as black sesame and walnuts. It is recommended to control the frequency of sexual activity, not exceeding 3 times per week. When experiencing persistent back pain or accompanied by symptoms such as fever and hematuria, timely medical attention should be sought. Pay attention to cleanliness before and after sexual activity in daily life, choose appropriate positions to avoid excessive pressure on the waist. Engage in 3-5 small swallow flying or swimming exercises per week to enhance the strength of the lower back muscles, and choose a medium hardness mattress for sleep. Increase the intake of spleen strengthening and kidney tonifying ingredients such as yam and wolfberry in the diet, and avoid excessive consumption of raw and cold foods.
