Hi there yes over time tightness has gotten better - it always feels tight, but I had acupuncture to break up the scar tissue, and return blood flow to the area, I also did lymphatic massage to move the fluid that's trapped there. If he had a lymph nodes removed on both sides then he's likely got a lot of fluid trapped there that will make things feel tighter.lymphatic massage rebuilds the pathways and allows for the lymph fluid to drain. My shoulder's about 98% I have good range of motion but I also have a pinched rotator cuff not related to the surgery but that hurts when I move a certain way. I have full range of motion with my neck.. Bending it back is a bit hard but the more you stretch it the better it gets. it's a long haul. Your hubby having had both sides done has to work twice as hard but it does pay eventually, not everything works for everyone but you never know until you try and and by trying I mean give it a few months to see improvement. Though there often is immediate improvement - continuing makes it last longer if you get what I mean - if you do decide to do have massage etc... Make sure you get someone who is certified and knows what they are doing. best of luck, and despite it all I do feel good.
