I have waves of heavy feeling which occur from between shoulder blades through to my lower back and makes one feel like someone is sitting on my shoulders and pull me back, almost to the stage of you wanting to collapse. If I believe in and out and bend over to touch my toes then the sensation goes away but not for long.

I thought it could be toxicity, but I also get very tired when walking - I have to wear a wedge in my right foot...got oestoarthitis in right hand side ball and socket joint...seen on xray - cartlidge has worn away...
