hi my name is jeff.i am a 59yr old male.i had been treated for chest congestin and chronic coughing,with some difficulty dislodging mucus.i was treated with 500mg of levofloxacin which cleared the congestion.approximately 2 days after finishing the med. i started experiencing a sharp stabbing pain radiating from the left center of my abdomen to my navel.mostly when i cough but most frequently when i attempt to sit or stand from a seated position.the pain is intense but only lasts for a second or two. is it possibly a hernia or kidney stone? i take one 10 mg tab daily of crestor.i had my gall bladder lapriscopicaly removed 3 yrs ago and have had left and right groin hernia repairs approx.5 yrs ago.i am a cigarette smoker(35 yrs.) but have successfully cut down to several per day those few are tough to give up but i'm confident! thank you for donating your time.it is appreciated!
