Big Fat Pain in the...Shoulder??

Thanks so much for your well-wishes and for thinking of me. I'm happy to say I have a lovely uterus, clear Fallopian tubes, and two lovely ovaries. I'm also happy to say I made it through the procedure just fine, and honestly, the worst part was the speculum. Minor cramping upon insertion of the saline solution, a little bit of spotting till now. Uncomfortable, but really not painful. Thanks for everyone's great suggestions; I did take pain-reliever beforehand, and the pad was definitely a must - I felt like I was "bleeding" saline solution the whole way home.

I'm pleasantly surprised by a lack of cramps or pain "down there," but I'm thankful I'm not having any...because I don't know if I could tolerate it on top of the massive, paralyzing pain I'm having all through my right shoulder and side.

I've googled all sorts of search queries, asked my doctor parents, called the clinic...but I have no idea what to do for the pain. Immediately after I got into the change room, I felt a sharp pain in my shoulder, which I thought was odd. Out in the waiting room, where I was told to rest for 15 minutes just to make sure everything was okay, the pain spread to both shoulders. DH suggested that I was probably just tensed up during the procedure, since I was so nervous about it. He rubbed my shoulders and back, and I felt better, and we got in the car and drove home. As soon as I stepped out of the car, I realized something was wrong. I had sharp pain all the way down starting at my neck and down through my shoulder which was intensifying as I was walking. Came home, called my mom, lay down, called the clinic. The doctor's office said sometimes the gas/air bubbles used in the procedure to see the tubes escapes into the body and moves upward. Hence the massive pain whenever I am upright, and the even more massive pain when I try to move around. They said it could last from one to three days. Prescription: lie down flat on your back.

Now, I know I said I was looking forward to relaxing and being pampered by DH. But I most definitely was not looking forward to three days on my back. The pain is excruciating; I've never felt anything more painful in my life.

Nothing I read online, no one's blogs, no one's comments, no literature from the clinic mentioned this at all. Have any of you ever heard of a reaction like this? Has this happened to anyone else? Any suggestions on relieving the pain?
