(Concern) I often get cramps while sleeping at night.

It seems to have been about a couple of months... I often wake up in pain from cramps while sleeping at night. In the past, I occasionally had cramps when I was very tired, but it was really rare, maybe once a year. However, recently, it seems to happen about once or twice a week. I already have insomnia and can't sleep well, and even when I manage to fall asleep, I wake up due to cramps, which greatly reduces my quality of life. I try to push my foot against the wall and relax to avoid waking my family, but I keep breaking out in cold sweat... I'm thinking I should see a doctor. I walk about 10,000 steps every day and move around a lot, and I often do stretching, so I wonder if this could be the cause. Should I perhaps move less? Or is this an inevitable symptom of aging? I'm afraid I might wake up again tonight due to cramps...
