I started physical therapy yesterday. It turns out that it is not sciatic nerve pain. I have a weakness in the SI joint - this is the joint of your spine and pelvic bone. The ligaments have loosened which we all know if common in pregnancy. However, the muscles are overcompensating for the ligaments and tightening - thus giving me pain and limited mobility. So, as of right now I have to do PT twice a week and exercises at home 4 times a day to strengthen this area. It hurts to do them, but if it pays of in the end, it is worth it - right?
