I sprained my left knee and can't squat.

According to your description, I can feel your mood now. Fortunately, we have the same hobbies and similar experiences.

Then I don't want to say more, just want to write something useful, hoping to help you.

First of all, I am not a doctor, but a patient friend who has similar experience with you! I just finished arthroscopic surgery on my left knee and am recovering, so I think I can understand your feelings and know more about this knowledge than more people. For this reason, I also read related articles. Well, I'd better tell you something about yourself.

According to the symptoms after your injury, I suggest you go to the hospital for magnetic resonance examination at once. I can't see it in other films. Injuries like this are likely to be ligament rupture or tear, or meniscus injury. Therefore, we will not consider the specific injury for the time being. When the test results come out, you will have a bottom in your heart, but what is certain is: "You are injured." So, there is no need to worry too much. We should not listen to other people's hearsay until we know it clearly. After all, he is not a professional and sometimes delays his illness.

If the disease is usually mild, the doctor will advise you to treat it conservatively. If it is serious, the doctor may advise you to do a thorough treatment (surgery) for future physical examination, and don't suffer from this injury (a long illness is usually likely to recur). Does the operation sound terrible, but I tell you it's not that terrible. This kind of operation belongs to minimally invasive surgery. It's nothing. All right, not much to say. After all, you don't know your illness yet. It may be a waste to say more. Wait until you know your illness, and then make plans. I wish you a speedy recovery!
