OK so I'm getting used to taking bloods now and mastered the technique but I bruise everytime. I've turned my machine to 1 which is the lowest its helped but I'm still bruised. Given I sometimes need to do 4 readings a day I'm really struggling. I swap fingers so there having a bit of a rest but the brusing is staying for a week. I'm very petite and have childlike hands so not sure if this is why. Is there anything that can help?
