Since then it has got worse as years have went past and in the past year or more the problems have become have at times made it impossible to move for a few minutes and after making me in capable of walking faster than a shuffling forward. In more detail I am unable to move my legs, back or neck because it causes high spikes of pains with even a cm or so of movement. The lower back pain is constant and moves around the back side of my waist it also spreads to my legs at times. I nearly always feel fatigued and get sick all the time with the flu . I have also experienced back spasms which lasted a day and required me to go hospital where I received some anti inflammatory tables near unbearable back pain lasted for a few more days after that. I been doing all types of stretches for years and tried to get involved in sporty activity it last for short period then downfall pain or flu comes after a 1-3 weeks. The back stretches cause more pain at the time and after.
