Hi, I have ddd for 10 years but I was careless, I did everything my first dr told me not to do, because 2 years after I consulted a second dr, and second dr told me I don't have any ddd its just in my head. So I stopped physiotherapy exercise, I climbed stairs and bent down, picked heavy stuff, did heavy packing and moving related stuff happily.. now I started hip pain and knee pain on right side, third dr told its Exaggerated Lumbar Spondylosis with Lordois and osteophytes at knee.. he asked me to wear belt .. I am doing physiotherapy and use massage gun at night.. is it safe to use? Any other changes I need... please kindly support with some suggestions, God bless
