Patients with uncomfortable legs can’t sleep, and this condition may first be caused by overexertion. If the patient has performed heavy physical labor or strenuous sports during the day, it may cause lactic acid accumulation in the leg muscles or lead to leg muscle strain, which may lead to leg pain symptoms. The patient’s leg pain is more pronounced and may cause insomnia. In addition, if the patient has long-term joint strain, causing osteoarthritis of the knee and other osteoarthritic diseases may also have symptoms of leg discomfort. Leg discomfort may be aggravated by cold or exertion. Some patients suffering from rheumatoid arthritis, gouty arthritis or lumbar disc herniation may also have symptoms of leg discomfort. In addition, patients suffering from lower limb vascular diseases such as lower limb varicose veins may also experience swelling and pain in the lower limbs due to poor venous return. So this situation also needs to pay attention to rest and avoid strain. In addition, patients need to go to the hospital for relevant examination according to their symptoms in order to clarify the diagnosis and carry out targeted treatment.
