Hello, Yes first be sure you have crohns before starting Remicade.
The office that I work for gives Remicade. We give it for Rheumatoid Arthritis patients and also crohns patients.
All drugs have side effects. Just be sure to have a TB test and chest x-xay before starting treatment. I'm sure your Doctor will tell you that. Our patients do very well on Remicade. We have had some people with reactions as well. Rapid heatbeat and vomiting. A nurse will be with you at all times and you will be premedicated just incase of allergic reaction.
I think Remicade does wonders for people that suffer in pain. But the choice is yours. As far as the fissures go. I had major problems with them and suffered for 2 years in pain. I had to get surgery...I tried everything.
The surgery (LIS) went very well and I have my life back. I can't believe I waited so long to have it done. I'm 100% better.
Good Luck...
