thanks for all of your great advice. i have had endometriosis too and am concerned that that is back again. already went through two major surgeries for that and the pain i have feels similar to that but when i mentioned it to drs they didn't think it was what i had. and yesterdays pain was the worst ever. it was as close to a ten as you can get and it made my rsd flare up. lasted all day but today it seems a little better but i am very nauseas today. i my have to go back to my endo surgeon and see what he thinks. i'm due for a yearly check up with him anyway. thanks again for all of your help. wishing you all a painfree as possible day today.
