It is not normal for sciatica to appear in early pregnancy, and patients are prone to such attacks at this time. It may be due to a lower resistance, followed by muscle spasm in the posterior lateral hip or aseptic inflammation, which may irritate the sciatic nerve and lead to radioactive pain, numbness, weakness and other symptoms in the area where the sciatic nerve is distributed. Patients with this disease must be treated as soon as possible, because it can cause very severe pain and can rapidly worsen in the middle and late stages of pregnancy. After the onset of the disease, it is important to go to a regular hospital orthopedic clinic and cooperate with the doctor to do a series of treatments to try to control it in a short period of time to prevent adverse effects on the pregnant woman herself or the fetus.
