Wishing your family members a speedy recovery. Your son in law may still be in a lot of pain after his knee surgery and that could be why he isn't sleeping very well. Maybe he needs some stronger painkillers to see him through the night. I have had two knee replacements and it is very painful afterwards, especially having to do the exercises. Once it has healed though there should be no pain and he can then build up his muscles and be much fitter than he was before surgery.
Our main concern now is that the second heart surgery on our grandson was also not successful. We don't know what the next step will be. But he is back to school also and keeping very busy. We just pray.
