I been reading a bunch of threads, and it all says lower back pain. I never get lower back pain. I tweaked it on monday my middle back muscle its on my right side where the rib cage is under my shoulder blades but more to the side. Today i felt a bigger tweak.. I dunno if its a pull or not. But i recently switched to a PS6.0 85 from a TI radical oversize. This is about my 7th time playing since the switch. Now i have read people recommending icing it and rest, but is there anything else i can do to speed up the healing? cause i really want to get back into it. BTW my service motion is Sampras like, and i never had this problem before, i think i am getting old. But i do feel it when i am trying to turn and swing the racquet. Its hampering my ground strokes too.. Today it hurt so bad that i started to lose my breath, but i still played thru it. Also some times i get side cramps, like right under the front of my ribcage.. Is that because i am out of shape? anything to stop that as well? It hurts to breath sometimes when that happens.
