I was diagnosed with mg five years ago and without going into too much detail i eventually hadca ct scan of my chest which showed a thymoma on my thymus gland. In 2021 i had a thymectomy and have been in remission ever since with no symptoms. The thymus gland plays an important part in the immune system and removal of it definitely aided my recovery. At the age of 82 i am now in the gym four days a week and enjoying life. I still take mestinon and mycophenolate but weaned myself off steroids because of the horrible side affects. Having a good neurologist is also important. Best of luck
