Thanks to a small slip in some mud a few months ago, I'm on Warfarin for life. I'm trying not to let it dictate what I can and can't do, but need to take precautions, just in case. Because I have a high INR (my target is 3-4 for those that know) I'm at a pretty high risk of a bleed on the brain if I hit my head hard. I'm wanting to get out walking more this winter, and of course, that means probably walking on ice, and knowing my luck, I will fall. So, I'm wondering, would I do better getting a climbing or skiing helmet to protect my head if/when it happens? I will only be walking, mostly in the peaks, but might venture up to the lakes and cairngorms if I get the chance. I currently use yaktrax, to stop me sliding about too much on the ice, but would it be worth me upgrading crampons as well, just in case?
