“My back is tingling… Is it just fatigue or a sign?”

Lately, my lower back keeps tingling, making my daily life uncomfortable. It's fine when I'm still, but when I stand up, sit down, or stand for even a little while, I feel a tingling sensation, like an electric shock, running down my lower back. At first, I thought it was just fatigue, but since it keeps happening, I'm worried it might be a herniated disc or muscle problem. Stretching only provides temporary relief, so I'm constantly debating whether to go to the hospital.
