I have been injecting Rebif for 2 years now. Tonight was the first time this happened and I'm just wondering if anyone else has experienced it.

I did my injection on my stomach. It burned, more than normal and as soon as I withdrew the needle I started to bleed, a lot. Then a bump formed under the skin larger than a pea, smaller than a marshmallow. It happened really fast and kind of freaked me out. My DH told me to rub it and after about 5 minutes, the bump started to decrease in size. Right now it feels like a soft pea under my skin.

Anyone have this happen to them? Is this something I should be concerned about?
