Hey guys. I'm a 24 year old male, fairly healthy. Over the past couple of weeks I've been noticing my sides hurt occasionally. I have been coughing, possibly allergies. Sometimes it almost feels as if my left side specifically has gas bubbles under it, and it seems to gurgle. Almost all the way up to my armpit. It comes and goes, and isn't really all that painful, more annoying. I was at the Dr last week and said my lungs sounded normal. Anyone have any ideas of what it could be?
