Earlyer today a jabbing pain started in my right side, just around my rip cage. Whenever i tense the muscles to laugh is when it starts. I dont really know if this is usual, seeing is how the pain increases pretty sharply when i lie down. I am currently taking Spironolactone, and i've read that some of the side effects are muscle cramping...but I've been on the medication for over a month now, but just reciently increased my dose..Im just wondering why it would it start now? My first thought was that I maybe had too many veggies or blueberries..digestive problems maybe? I have no idea.. I also have insomnia, so perhaps this stress is causing all these cramps? Any more info on this would be great, as my last resort is my doctor.
