On July the 10th I pulled my lower back muscle doing the squat machine for the first time. After that day, I developed pain all across my lower back. It took me 3-4 weeks to get the pain away. Now, I'm experiencing electrical shocks around the lower back, sometimes on my upper body and on my legs (rarely). I developed upper back pain too. I'm not sure if it's connected or it has to do with my work where I stand long at customer service for almost 7-8 hours every shift. I been to my doctor and a chiropractor and they stated it was mechanical lower back pain. I did a x-ray on my lower back and they haven't found any split discs. Currently, every morning that I wake up I experience lower back pain (feel the pain where it used to hurt) and throughout the day from the moment I start walking it goes away.
What I am wondering is that - is my lower back and upper back connected or is my upper back related to my work?
As well, why is the lower back pain occurring in the morning?
I been to the gym a little bit but nothing serious. Now I'm off the gym and waiting to see my sport medicine doctor to rule out further diagnostic and tests. What is happening to me? I'm becoming stress, anxious, and paranoid about my back. I hate having this pain. What should I do?
