Is this spine related pain?

Can anyone who has knowledge and/or experience kindly advise?
1) What is a MRI cost for spine in Bangkok and, which hospital and spine specialist is recommendable?

My back especially around mid-back has been very tired, ached, pressured and uncomfortable even sometimes very early in the morning, for about 8 weeks (since around 5 October 2017) even when my usual sitting and standing.

It is coincidence with EMG testing (a needle was inserted on 3 different area on my back) that was done on 3 October 2017.
2) Is it whether this EMG testing was related to my back’s tiredness? It is because a needle was inserted around the edge of or so close to my spinal cord when the simultaneous simulation of some back muscle’s movement by a nurse that might further cause some impact on the inserted needle and, its surroundings and underneath that might be a bone or nerve.
3) Is this persistent tiredness and ache of my back related to my spine?
Red spot is where a needle was inserted and finger point to my spine.

Thank You,

Merry Christmas and Happy New Year.
