Thanks vlk20.

The doctor used a GE Optima CT Computed Tomography scan machine to do the medial branch blocks of left T3/T4 facet joints. The machine looks similar to the one in the attachment.
There is hardly any pain where he injected, but before he injected, he needed to find out from me where was the pain. So he started pressing from T1 to T4 to get an answer from me in regards to the pain. What is hurting me is T1/T2. He pressed rather hard. I wasn't impressed.

I have taken a Targin SR 10/5 tablet and after 6 hours I just feel slightly drowsy.
I was thinking of taking a second tablet, but I am worried about taking too much. I read that you can take up to 20mg a day safely. My lungs are pretty good because I was a long distance road bike rider, anything from 50km up to 170km in a day.
