I caught a cold, nothing extraordinary under normal circumstances, but extremely painful when you're on immunosuppressants. I had to quit my lovely meds for two weeks while my body fought a cough and sniffles, only it's not just a little cold for an arthritis sufferer. Without the Enbrel and Methotrexate the arthritis pain returns full force within a matter of days. I was healthy enough to receive an Enbrel injection a couple of nights ago and I woke up the following morning with relief in my joints. Oh how I love 21st century medicine.
