OMG... i have had the exact same thing only on the left side. I also have no idea what it is!
I went to the ER last night to get a quick strep test. It was negative, but because I have been really tired lately and have had a sore throat for 3 weeks, they did a mono test. I will know today. Funny thing is when I did research about mono, the spleen is right where my cramp is! And I get it when I bend over...probably putting pressure on it! Will let you know later what my findings are!
i too have this same problem. It doesn't happen all the time, but it is whenever i am reaching for something. But i can be reaching to the left and the right side goes into spasm. Same it is so painful i cannot move. Gonna have to get to doc and see if he has any ideas??
I just experienced the same pain on my right side. It feels just like a gall bladder attack, but subsides within 2-3 minutes. I thought it was my gall bladder the first time I had this, but I soon realized that it would happen when bending my upper body a certain way. Tonight, I actually felt a "glug-glug" when I straightened my body out to deal with the pain. All that I know is that this pain is intense!
