Day 32 on Enbrel - Another flair up due to traveling?

Now I'm in month 2 of taking Enbrel. The first month had some downs but mostly ups! As you can see in this posting my knee is continuing to improved from the flair up I had a few weeks ago. Today, I landed in Las Vegas for work. Only after a couple of hours of being on my feet, my joint at the end of my pinky toe is hurting and pretty bad. This joint has been a problem since the beginning of my rheumatoid diagnosis a bunch of years back. It was doing well, especially after taking Enbrel. However, for some reason it's acting up today. I wonder if it is the travel and stress? Has anyone gotten flair ups from traveling? I see my doctor this week and will ask her.

Taken last Wednesday before my 4th shot.
