Yes, it can happen. After years of being on warfarin, I had to undergo some plastic surgery to remove a skin cancer just under my eye, and to do this, I had to go off warfarin for a week, so that I would not bleed badly and effect the operation or the healing of the wound. In the past, I had been taken off warfarin for three days for other matters, but a week caused my GP some concern, and so he said, well we will just use Clexane. I had no idea what this was... it turns out it is a daily injection. I assumed he would do it - but no, you do it yourself. Shock horror. Well in a nutshell, it is not as bad as I feared. There are lots of YouTube videos with people injecting Clexane (for example http://www.youtube.com/watch?v=4YtO7K2vkcI ). Do a search, and you will find it valuable, and it will give your confidence a lift. The injections are a bit horrific the first time or two, and you certainly can get bruises - one of the videos says to introduce the needle very slowly, and inject slowly - this I did not try, and perhaps should have. On injection, there is a stinging sensation for about 15 minutes, but no great hassle. Clexane contains the active ingredient enoxaparin, which is a type of medicine called a low molecular weight heparin. It is used to stop blood clots forming within the blood vessels.
