Well, this is where I am at in my training. Pull my back the other day and was in so much pain had to have the ambulance take me to the ER since I couldn't get off the floor. Could of used a life alert necklace "Help I've fallen and I can't get up" I got the chills which caused back spasms to kick in which had me on the floor with a shirt in my mouth screaming whenever they hit.
Spent day in ER having x-rays and mri done. I have degeneration in lower back and my L4 has a 3mm bulge. Waiting to hear back from back specialist, hopeful can take of it without surgery. Until then I'm on the mend
