I have taken 3 shots of Enbrel. The first time I only had a bruise. The second time I had a 2 inch circular red rash that took 2 weeks to almost go away completely. The third time I had a swollen 2 inch circular rash after a couple of days & then a couple days later it started to itch. Now the spot where I had the 2nd shot is starting to itch also. Does that mean I am allergic and have to stop taking these shots?
