I was doing very well with my SEP and Reading through HBP but yesterday when my Cousins Came to see me, I sat in the Chair for long time showing them some stuff on lappy and after they left I had this muscle spasm in my low back and didn't recover from it since yesterday. Whenever my recovery is jolted by incidents like these, I forget all the good work I have done so far for Couple weeks and recovery I made. This is so nasty. Whenever the pain comes back all I think is structural. Its hard to sit, stand or sleep without pain. I cant engage in any activity too due to pain. Even Pain killers don't work. Please give you suggestions.
