im 25 white female whos obese with diabetes, hypothyroid , epilepsy , ibs , among other illnesses. I was recently constipated and it took 3 days just to finish one bm. I ended up drinking half a bottle of magnesium citrate just to get this little piece of bm out. I dont remember straining that much, but now my whole upper half of my body feels weak and is very painful to cough, sneeze, laugh, and breath. What could be wrong?
