I've been on Humira for two months now, and Imuran as well. And I'm starting to get some interesting side-effects. I noticed my vision is getting blurry, nothing terrible just to the point of annoying. Also, have this pain in my knees and elbows that, at times, is quite excruciating! I was wondering if anyone else has had to get glasses because of this, and if the joint pain is just something I need to get used to. Or if it will go away? One more thing, under my tongue seems to be puffy and irritated. Anyone else ever get that? Any help would be greatly appreciated! Thanks!
