I need help/advice, the pain is getting worse!!!

So, since about 20 weeks I have been dealing with what the doctor tells me is "round ligament" pain... It the beginning it was more of just a pulled muscle pain and was worse if I did too much! Well lately I can hardly lift my right leg... I mean to roll over in bed, put the recliner down, and even some as simple as using my leg to push open a storm door almost drops me to my knees in tears... I bought a support belt and it helped some at first, but is offering zero relief now... Soaking in the tub hasn't seemed to help but it also requires use of and lifting of that leg to get in and out...
