I have had upper left abd pain and upper left back pain for 2 nights. It stops when I stay sitting up, so slept in a recliner last night. Took 500mg Naproxen, also. No SOB. + indigestion. If wasn't a weekend, I would have gone to ER. I am a 61 y/o female w/ high cholesterol, but normal b/p and glucose. No pain in the daytime, but exhausted from poor sleep.
