First off I’m sorry to hear your son has been diagnosed with MS. With that said, my wife has lived with it very well for the last fifteen years. See was in her mid 30’s when see started having symptoms. Tingling in legs was the main sign. Good news is she may only have symtoms once or twice a year and is usually brought on by stress (not always caused by me). I give her a shot in the legs once a week since then with a drug called Avonex. The good news is she is still beautiful and strong and you’d never know. When she was diagnosed with this they said that at her age the effects of MS is very minor to compared to if you get your younger. Hopefully you son will have the same outcome. Our God is an awesome God at all times. We will pray for you and your family.
