I keep having a lot of problems with my finger nails lifting off the nail bed whilst climbing. It's not a huge issue as it only lifts off a little bit but it lifts off just enough to bleed a bit and be quite painful. This mostly seems to happen on my index fingers (e.g. see mildly disgusting photo here: https://www.dropbox.com/s/pg5vuimwqtxov77/fingernail.png?dl=0). Has anyone else experienced this? Is this a result of over/under-trimming my finger nails?
