Not sure if my monthly infusion with Tysabri is affecting my anxiety level - it s hard to find long term data. Lately, I ve noticed to be more so than in the past. Has anyone else taking this medication noticed this? I ve been on it for about 7 years and absolutely love it - it s been helping me live a normal life. And I play in disc golf tournaments (so much fun)!! Any info. would be helpful. Thank you.
