Has anyone any experience of these? I have what I think is a bakers cyst(a cyst behind my knee). Google tells me that there isn't much that can be done other than icing it and resting it. It's seriously painful at the minute, I can't bend my leg properly, I can't walk properly. I'm debating whether or not to go to the out of hours gp but it seems pointless if they can't actually do anything? Did you have one? Did it go away by itself? How long did that take? Any experiences welcome!
