If it's not one thing, it's another

I have been riddled with muscle cramps since Thursday. I think it's just muscle spasms at least. It has been difficult to breathe because of the restriction on my right side, high up, chest level that feels like a knife in my lung. Today the pain wrapped from the front to my back shoulder blade, up my arm and into my neck. Michael and I tried stretching and massaging it out, but nothing works. If I sneeze it's excrutiating as well as if I twist or bend or reach. Good grief I'm tired of having issues! I'm worried I might be really low on potassium or worse, have a swollen gallbladder. I had to call the doc today because I couldn't stand it anymore. He gave me 5mg of Valium to hopefully get me through the weekend and then I'll see him Monday. I think it's helping. If anyone has had similar experiences, I'd love some advice. I'm eating bananas like a monkey and drinking lots of gatorade.
