Hi guys. im new here. Writing is somewhat painful for me, so I will try to keep it simple. Could someone please tell if they can relate to my problems and possibly what was their diagnosis?

I am 26, male. As for my problems... Let's say it all started with gradually increasing back pain last summer. It was caused by hard physical labor (moving company) abroad plus bad furniture that I had to use where I stayed (bed, chair, pillows etc.). I have bad posture (deep lower lordosis) and always experienced some degree of low back pain after prolonged standing or walking, so I wasn't too concerned when It started hurting me after work. It never was really painful, just unpleasant. After a while I noticed that this pain would go upwards toward my head, making my spinae erector muscles really hard and stiff - but still not that painful unless I sat in my chair that was not so comfortable. I knew this was not good, but I had to work only one month more (the job itself was not painful at all), so I thought "not a big deal, I will get better home". When I got home it did seem to get better with time, my muscles loosened up a bit, the pain was decreasing.

But here is where this all gets weird and seemingly unexplainable. I had moderate pain and stiffness only in those two long muscles that run along spine. I didnt have any nerve pain, no acute fits of spasm. Now, as the pain subsided, it began to wonder towards my hips (muscles at the side of my abdomen got tense and hurt for two days), then ribs, then I had some pain behind scapula, my shoulder hurt a bit. The pain resembled that when you exercise and feel the tiredness accompanied by weakness. It would go away, if I lie down flat on the ground and then move elsewhere. Every place the pain went to, it seemed lesser and lesser.

I dont like doctors after being misdiagnosed on many occasions, so I hadn't seen one that far. I though that this is natural, that muscles re-adjust somehow. What I didnt want to acknowledge up to that point, is that every spot the pain went to - left muscle weakness and stiffness. It just seemed too weird to accept and I decided not to bother. Pain was going away - thats all I cared about.

I was working out the weaker spots and it all looked as if getting back in track, until one day I woke up with really stiff neck (not painful). I freaked out and made an appointment to get an mri of my spine. In the meantime, just like the other muscles, my neck got really thin, all those tense muscles that I got just disappeared overnight. Not only those - ALL the muscles in my back were much much smaller.

The mri of my spine showed no significant changes, nothing that could cause those symptoms. Every doctor I saw told me to either get a mri of my little brain or get some PT. Since im my mind all of this was mechanically inflicted, I figured they won't find anything in the brain and I went with physiotherapy. The guy told me I have lower crossed syndrome and made me stretch a ton. Then we continued to strenghtening exercises. But just like before, after some improvement, my muscles get weaker no matter how hard I train. Even if I perform better at the training, I have increasing problems with dailly tasks. Everything just seems getting heavier for me, I can feel the weight of my own body, and its not nice. I get tingling and burning sensations all over.

This all lead me to the conclussion that I must indeed have some musco-sceletal or autoimmune disease. It just doesn't make sense. Why would my hands and calfs get so weak after some trauma to a completely distant muscle? I also developed slight sight loss and mild tinnitus. My b12 vitamin level is 550.

If anyone could shed some light on this one, I would be very thankful.

thank you in advance
