Hello, I'm not exactly a stone skin person, and I've gone through an EKG/Chest X-ray/Heart Monitor and all have come out well, curious however I have two light sore black and blue marks on my arms near my muscle, and on my right leg I have about four very light black and blue marks that hurt a little, are these blood clots?! I'm still suffering from anxiety as well, been doing more working out lately... I wonder if I bumped my whole self when I was anxious? Any ideas? Thanks.
