What could the problem with my legs be related to? Is it some kind of disease?
I think it's some kind of syndrome, because I think it doesn't depend on what kind of lifestyle you have or what kind of weather you're having. Or I think it's something that usually lasts a couple of hours, 24 hours at the most. And I see that you've been concerned about it for days now. So I don't know exactly what it is, but I can definitely advise you to put all speculation about the weather aside.
I've heard of some kind of restless legs syndrome, I could tell you it's not, if at no point did you say that it usually manifests itself at night and also, by the way, it happens in the morning. This, I think, is related to this particular syndrome. Maybe google it in more detail, too, what it means? After all, I can't tell you in Details. But for some reason I really think that's what it is.
There's nothing wrong with it in general, but the worst things it does is it keeps you awake.
This case is more like looking on the Internet, something from folk medicine. I think it is not serious, in general I prefer not to take any medicine, because in my opinion they are detrimental to health. So it is better to look on any forums that are associated with folk medicine, what is the case and what herbs to treat it, thinking that something to do with nerves and any herb that is suitable for it, can cure the case.
Unfortunately, this kind of problem has happened to smart people I know. I want to tell you that it's not a very common problem, but I am familiar with it. It's called Restless Legs Syndrome (RLS) . It's not a very pleasant problem, which also causes insomnia. The main reasons why it occurs in women is drug intake, pregnancy, especially the last trimester. Women are more likely to experience RLS And it is a known scientific fact, I want to tell you that you have to fight this thing with medication. Because in addition to the fact that you are bothered by your leg about you will also be bothered by irritability and insomnia. This problem is very broad, and it affects so many aspects of your life, and I think you can learn more about this problem here https://gojourney.app/restless-legs-syndrome/ . After a friend of mine recently got this syndrome, I was surfing the internet with her and found that article.
