34 yr old female with excruciating low back pain?

i have been recently diagnosed with a spondylioarthropathy. some kind of autoimmune disease, causing low back pain and uveitis. treatment to stop progression of disease is Enbrel, humira, or remicade IV every month. how safe are these medications. I drive a school bus for a living, and was told that I can not come into contact with "sick" people, because it could jeopardize my life. SOOO scared please help
