I noticed you are on remicade. When I was on remicade for 1 1/2 years, I did have tingling in my arm and lower leg. I also developed a twitching by my right eye. My GI sent me to a neurologist who did a nerve conduction test. This turned out to be ok, thank goodness but I did notice that when I stopped the remicade the tingling and twitching also went away. You might want to mention your symptoms to your GI. Interestingly enough I am now on humira and the twitch by my eye has returned. All the best to you!
