Extreme leg pain

I'm having issues ya'll. The other day I was having slight leg cramp pain and then as the day went on my left calf had a surging knot like pain when I stood up and it hurt very badly and took a second to feel normal to walk again. I slept with my legs lifted a bit that night, took a hot bath and rubbed them. Today my legs was fine but again as the day went on, pain. This time both legs and in the left it feels as if it's going into the inside of my foot/ankle. It hurts more in the whole calf as well. I can feel my heart beat in spine too 😂 any ideas ? I'm gonna take a hot shower, severally stretch. Trying to drink a lot of water, and plan to have my legs lifted a bit when I sleep again tn. They almost feel constricted the more I try to move. Hesitant. I have things to do tm and it's going to be a little rough and tiring. If they don't stop hurting every time i try to do things I'm gonna struggle.
