You definitely need to be tested. Before I had my first Remicade treatment, I had to have a TB test and a chest sxray. My chest xray showed a lung nodule. After the xray, I was refereed to a lung specialist. He refered me for a CT Scan of my lung and it indicated that I had previously had histoplasmosishs, probably as a child. I was negative for any active disease. I had to have several more CT scans to ensure the lung nodule was not changing after I started my Remicade.
I had to stop the Remicade due to reactions of high blood pressure, hives, breathing problems. I am currenly taking Humira injections and an doing well with Crohn's Disease. However, my joint pain nd fibromyalgia is horrible.
Hope everything works out for you.
