acetabular sclerosis and lumbar spondylosis

hi all. among other problems i have been diagnosed with acetabular sclerosis and lumbar spondylosis. some days it doesn't affect me much. my hips and knees ache if i do too much walking but another day i might struggle to walk from the lounge to the kitchen to put the kettle on which is probably only a distance of 12 foot. will wearing a back support when i walk help makr things easier. i also have arthritis in my neck which causes all sorts of problems will wearing a collar help, or does wearing supports make things worse.
