I had an accident skiing a week ago and landed hard on my collar bone. Large lump developed over collar bone, very painful, restricted movement in arm, a lot of bruising and swelling which has moved down my chest as the week progressed, I had x-rays on the day of fall which found no broken bones. I just today ( a week later) had a moment where I felt nauseas, nearly fainted and sweated a lot. I sat down, drank water and almost immediately felt better and now feel fine, except y hands are cold. Is this connected to me fall a week ago and is it anything to worry about? thanks
