Patient: Description (onset time, main symptoms, hospital visited, etc.): After getting up in the morning to go to the bathroom, my back suddenly hurts so much that I can barely stand up. I’ve never experienced such a serious condition, and I’ve never had any injuries to my lower back. I’m only 20 years old female, can you tell me what’s wrong with it and how to get first aid? Doctor: Hello, I don’t know how much you weigh, whether you are fat or not, do you usually engage in any sports? Your case may be a certain incorrect lumbar posture caused by a small joint disorder or local synovial impingement, there is no turning over when the pain will increase? Don’t be too nervous, this situation can generally be completely relieved by bed rest, bed rest time should be calculated by weeks (usually more in 1-2 weeks to relieve), so bed rest just 1 day is certainly not possible, during the bed rest period need family to take care of you, avoid walking on the ground, at the same time can oral meloxicam 7.5mg (1 tablet), twice a day. After the symptoms have subsided, you can go back to the hospital and check the MRI of the lumbar spine if necessary to find out the condition of the discs. I’ve been in bed for a few days, and I’m getting better every day. I’ve been able to go out now, and the doctor didn’t take any pictures, but just said it was a lumbar sprain. …… This answer makes me a little uneasy, and I wonder if a lumbar sprain will be a habit in the future. Will I sprain it often? Will there be a risk of lumbar disc herniation when I get older? I’m very worried about this, and it’s really painful to have a sprain. My body is considered fat for my height, and I rarely exercise during the day. Doctor: According to your supplementary situation, I still suggest you have time to do an MRI of the lumbar spine, there may be some signs of degeneration of the intervertebral disc. The best way to exercise the lumbar back muscles is to type “lumbar back muscles” in Baidu, and there are many ways. I recommend swimming exercise, better.
