3months back I had spinal disc bulge or prolapse I found very hard to stand and do normal activities,but now iam able to do normal activities I think the bulge had decreased in size .But when I stand do the work the muscles surrounding the disc area are tightening, is it a sign that the disc bulge is healing or something else?Normal activies includestanding,sitting o.k but while bending it s stiffening my back .
