I have MS and a gym membership--and that doesn't oblige me (or you, in a similar situation) to serve as a public resource on either of those topics, or on the combination thereof.
If friends ask, I'll usually answer. When I got together with an old college friend this Spring, after conversation on other subjects, she hesitantly said "Can I ask you a personal question?" When I said yes, she asked me for hints and advice on what to do, and not do, with/for her cousin who has recently been diagnosed with MS. I gave a few; including "Don't panic", the comment that she was doing the right thing by not expecting her cousin to be a general-purpose MS information resource; and not to burden her cousin with having to reassure other people about her disease. She's newly diagnosed, she needs to be reassured, not to have to reassure everyone she knows.
But she knew that it was a somewhat personal question ("somewhat" because she wasn't asking for details of my symptoms, emotions, or coping strategies), and she was prepared to take "no" for an answer.
