Dealing with mild (diaharea)bouts, and diagnosed with mild/moderate Chron's disease. I'm so afraid to start Humira because of how it wipes out your immune system. Normally never sick, and doesn't Humira make you more susceptible to diseases and illnesses? The doctor first was going to put me on pills but my blood work resulted that the enzyme in my blood will not accept the pills. Any info and sugestions are mostly appreciated, please help!
