Left ovarian cysts appear tingling, if the pain is not gradually aggravated, it is considered to be caused by the presence of inflammation in the pelvis. Ovarian cysts are caused by inflammation and need anti-inflammatory drugs for anti-inflammatory treatment. Clinical choice of broad-spectrum antibiotics, that is, intravenous drugs that are effective against anaerobic and aerobic infections, such as cephalosporins, combined with ornidazole or etimicin sulphate, are used for a period of roughly 10-14 days, and are regularly used in accordance with the course of treatment and should not be discontinued privately, or else they will affect the effect of the drugs. After the anti-inflammatory treatment is completed, it is recommended to stop the medication for one week and then go to the hospital for ultrasound to check whether the ovarian cysts have disappeared or shrunk. If the ovarian cysts have shrunk or disappeared, the medication is effective. If there is no obvious improvement, it is necessary to do regular ultrasound to check the growth of the cysts, and if they gradually increase in size to more than 5cm in diameter, they need to be surgically removed to be cured.
