After Humira break, feeling awful!

Hi everyone!

I was dx'ed with PSA and RA about 3 years ago. I started MTX and partially cleared up. Last year, the doc added Humira every other week. (So I was on 6 tabs of MTX every Friday and a Humira shot every other friday as well for about 8-9 months.) In the beginning of the summer, the doc wanted to add Humira weekly. Well, the mail order pharmacy messed up and I ended up not getting ANY humira until last week. I went 8 weeks without it! My question is, when I did take the shot and the MTX on Friday, I felt absolutely horrible on Saturday. (Usually Sunday-Monday are my recover from meds days.) Do you think it was from being off humira and then going back on?

Thanks for your advice! :)
