I am new to Mayo Connect....I have MS. I was diagnosed at age 32...had a large lesion on my cervical spine and was in the hospital for 10 days. Many symptoms, including weakness, loss of dexterity in my hands, the MS hug, fatigue. Took me a year to recover and feel like myself. I was very frightened and not at all certain of my future. I am now 62 and have done well with my MS. I have been on Avonex for almost 20 years. I have some parathesis/numbness in my feet. Recently had an MRI and the lesions in my brain and cervical spine are now smaller. Just wanted to post to let you know MS for some can be benign....I have a few issues, but nothing that stopped me from leading a full and normal life. I was recently diagnosed with degenerative disc disease and have been having debilitating back pain for 8 months. I was always worried about another MS exacerbation sure didn’t expect this. 🙁. But I will take it a day at a time as I did with my MS. I pray your sister does well...even if the diagnosis is MS. God Bless.
