Do you get 'more sick' if you catch something while on Enbrel? I have the cough and cold from hell at the moment, honestly feeling really rough. I've been on Enbrel a couple of months now and wondered if I was feeling so bad because of that, or am I just unlucky? Don't think I have a temp, just a horrible chesty cough and a rotten head cold. Also, I am due to do my injection again tomorrow, should I maybe wait til I am feeling better? Will doing the injection make me feel worse? Thank you. Kim.
