I have this really 'sharp' but more like 'annoying' feeling 'upper-back-left' pain than anything else, as I'm not feeling sick a bit and I'm perfectly alert and in fact want to be at work. This is the second time in 2-3 months.
// The region of the pain is on the left side of my back - 'middle-upper back' & 'about an inch left of the spine' - spreading an area of about '8-10 inches vertically'. I can't remember now how it cured the last time around, but I saw a physiotherapist then and visiting him actually 'worsened' the pain later. It stayed for 2-3 of days. //
It started really negligible, but now have grown to a point when I can't breath well if I try to relax-down my back or if I lie down on a bed. It's a sharp, oscillating kind of pain that's absolutely 'non-existent' at certain postures and 'too sharp to halt breathing' at other moments while walking or lying down.
p.s. I do smoke regularly (about 10-12 since last 6-7 years) but I can run most of my friend out on a flat-out run of 100-200 meters. I work out (not heavy but moderate) regularly. Eat well, very little junk foods. Body-Fat is about 12-14%
