Hi my name is Ivelin. I had x-ray to both knees and patellae lumbar spine , the results are for my knees: minimal medial compartment degenerative change and for my lumbar spine is: minimal spondylosis . My question is what s that mean and is it ok to continue to lift heavy louds, because my job is to lift boxes and build a pallet with them, I feel pain when I m doing that. Thank you for your attention!
