Hello, While at a gym today I was doing some deadlifts in a group class and on the second set I had a terrible back spasm in my upper middle left back that caused me to end the workout. I know the back is incredibly strong and I’m trying my best not to freak out over the incident, but it’s hard to to do so when every movement causes terrible pain. I haven’t done deadlift in years so I may have been conditioned to think I hurt myself. I’ve had TMS flare ups in the past but nothing that was directly related to an acute event such as this. I do check many common TMS traits being a goodist and perfectionist. My sales job has been extremely stressful as of late with a big sales pitch this week. Maybe it was the perfect trigger. Should I be concerned it is something more than TMS when I can barely move without severe pain? Thanks for reading and sharing any advice.
