so ive been sick with a cold the padt three days and ive had these constant headaches. Last night my right kidney was hurting so bad I couldnt sleep, it also felt like I was struggling to breathe. This morning I woke up with horrible cramping and pressure in my lower abdominal area(they say its from ligaments stretching but its concerning me). I am also having trouble breathing in my chest area, it feels like someone is pushing down extremely hard on it... any suggestions? should I go to the doctor, er? I'm just really concerned...
