I have Myeloma,  diagnosed in 2016,  9 months of Chemotherapy and then a stem cell transplant. 4 years in remission and the it crept back, currently on treatment that will last indefinitely.  The shaking comes with the medication unfortunately,  I have it all the time.i also have 6 collapsed vertebra in the base of my spine, went through 18 months to 2 years of pain was on pregabaline and oxycodin  tablets for the pain.  I found it really hard as the fatigue you go through makes it impossible to want to socialise or be social.  I found u just wanted to rest at home, I would make plans to meet up with friends and then just feel so exhausted that I couldn't face this. Just going to the hairdressers takes all my strength and then I am exhausted for a couple of days. When you go out you stress because you are trying to act normal  to put others at ease .  Remember your body is being bombarded by chemicals that kill your good cells as well as your bad cells.  I pray for you both. I am here if you want to chat, there will be loads of questions you will have if I am able I will share my experiences with you.
