Its upsetting as just wot.
Had it in 2001. Went in Gym and lost with Ayrobic 41 Kilo in 5 Month.Also grow 2 cm as Muscles build around Middle lifted Upperbody.
Backpain was gone as now Muscles holded the Upper Body and not the Spine.
Now Backpain here again.
Got me now some Heat Patches and put it on my Heels during i sleep. Fix it with Bandage. Works well.
