A bit of update - got MRI of the neck - no problems whatsoever (at least the one that could be seen on MRI) - so at least one good news.
However during my exercises yesterday managed to do something to my back again
Was doing sit-ups (not the normal ones, but the ones for people with back problems - like trying to sit on the toilet
- learned them during my rehabilitation) - and got pain on the right side of the back, however instead of stopping - I continued to exercise (call me stupid...) - now I have hell of the pain on both sides of the back, can barely stand straight - hope that it's just muscles since pain does not go to the legs and I can raise legs also without any issues. Then again - maybe my herniation got even bigger, but since its central - it doesn't affect legs. If pain persist - I guess I'll start with opioids - cannot afford to be out of work until my probation ends in 2.5 months... On the positive side - because of the pain in the back have no burning in the legs
