hi my name is Damyn. I currently take vyvanes. I used to be on the 20 mg but now I'm on the 50 and I've noticed a pretty bad random bruise on my arm. People told me I probably forgot but I would have remembered getting hit so hard to leave a bruise like that. it wasn't on me this morning. I could have devolved it through out the day and not noticed because I'm wearing a jacket all day. anyways, should I be worried/concerned or am I okay ?
