I'll be 27 wks on saturday. I didnt have this with my first. I know every pregnancy is different just like all our rsd is different. I do lay on my left side but this is a different feeling. Its like my tingling is from another weather change which is comin on tomorrow, but I have also had gastroenteritis and this is kind of like I felt then except almost my whole left leg is affected by it also. I did have preeclamcia and toximia with my oldest son but not until 38 wks. I know there isnt a lot of research done about rsd and pregnancy. Thats one thing I looked up right away when I knew I was pregnant again and there isnt any research on gabapentin and pregnancy. I got off that right away. Its like I have heartburn, bile taste and am walking on a water balloon strapped to my foot but my leg isnt that swollen and neither is my foot. Does this make sense? I am going to call my ob tomorrow if this doesnt let up though.
