I have got cervical long time back, bcuz it radiated to my hands as well, and few years later i found the similar pain rolling down to mt lower back and now it had radiated to my leg also at times, there is specific point which pinch pains, and there is a pinching and locking pain in the middle of the back, as well, like i have it right now.. also even i lift something heavy, climb stairs do even a little exercise or just bend for a little while and get up, i just crushes me with pain, and my pulse rate increases to extremely high levels.. my heart starts beating very fast and takes me a while to settle and breathe thereafter.. WHAT could be the probable cause .. could it be something major? I got a test after all this happened, for a long time and the doc founf that i had very deficient VIT-D (i.e 17.50) could this seriously be a reason? Bcz i still feel there is something major being undiagnosed? Bcz it hurts a lot in pain!!
