Severe round ligament pain

Ginny
Ugh! I woke up this morning to such pain on my right lower side. Very tender to the touch. But it just feels like it's pulling. Painful to walk. It's not as painful on the left side. I tried to soak in bath and that didn't help. So now I'm drinking water and have a hot pack on. Why is it so bad only on one side this morning? It's excruciating. Should I wear belly band? I'm 26 weeks.
