Severe pain on left side rib, swollen inside and with constant nagging headache. What could this be?
I am a 24 year old female. Woke up a week ago with a severe pain on my left side under my ribs front and back . Seems tender to touch , pressure and swollen inside. Moderate lower back pain accompanied with a constant nagging headache . Hurts to lay down , sit upright, and stand . Hurts to hiccup and sneeze . Pain has not lessened at all since it began only intensified. What could this be ?!
