Questions for people that have Multiple Sclerosis?

Let’s start from the beginning. I was diagnosed with MS 5 years ago. I do not take any injections because I don’t believe in being a Guinea Pig & I don’t trust the FDA but I do try & take care of myself such as eating & exercising correctly.
When you exercise do you notice that your symptoms get worse? For instance, I just got in to cycling & it took several weeks before I could fell my legs properly.
Are your symptoms worse in the Hot rather in the cold? 100 degree days for me are a killer it makes most of my body tingle (similar to your feet being asleep).
When were you diagnosed & how have your symptoms got worse?
If anything, what drug are u on & what effect has it had on u?
What has your doctor done to gain your trust?
Is there support groups that will support my decision to not trust the FDA & the guidelines they have given doctors? & no the National MS Society encourages u to be on the drugs whether they seem to help or not. Had a counselor their, been their done that.
