side effects from arava

I've been Arava for almost 2 months. Lately I'm having abdominal and upper chest pain. Also, I bruise extremely easily, even without any injury. Example: I kneeled on one knee to wash my hair in the tub. The next day I had a very large bruise on the area of my knee. The bruise is 3"by5". Also, on my upper arm I am getting dark bruises which surround my upper arm. The first one appeared about 3 weeks ago (and is still there and very dark). Then about a week ago I've noticed more bruises in the general vicinity.

Could this be a side effect of the drug?
