I wish I could answer your question but I too have a bruising problem that I want to know the risks about! I’m anemic and it definitely shows on my legs, I mean I know everyone bruises from poling but for example yesterday after practicing I had a sort of hot-cold burning pain spearing through my inner thigh, it felt like I was internally bleeding! It did eventually go away so I’m gonna wait to see if it happens again before I go to a doctor, but I’m just wondering if I can do permanent damage by bruising too much too often?
