pain and not feeling well

THIS PAST YEAR I HAVE HAD A FEW BOUTS WITH MY LEFT SIDE HURTING AND A LITTLE PAIN IN MY RIGHT CHEST AND BACK BUT IT WOULD GO AWAY AFTER A FEW DAYS. THIS TIME IT SEEMS TO BE A LITTLE MORE PAIN THAN BEFORE AND IT HAS BEEN GOING ON NOW FOR ABOUT TWO WEEKS. AT TIMES IT DOES SEEM TO EASE UP. SHOULD I TRY A FUSH.
