Hi, I am very concerned about my 30 year old son who has recently started to experience pain and 'cracking' in both his wrists and ankles. He has a very physical job and it is causing him difficulty. He is reluctant to go to the doctor at the moment as he is due to start a new job shortly and doesn't want a health issue on his record before receiving a signed contract. I appreciate that he is an adult but sure all the mums out there understand that you never stop worrying about your children whatever their age! Can anyone help please?
