Anyone else had something similar? I've had this a few times and it is really uncomfortable for up to a week especially as I cycle a few times a week. Then it just disappears again for a while. Before it has been on the left side and the last time was October last year. Has returned now on the right side, but it's on its way out again (as in, not uncomfortable sitting or cycling any more but I can still feel it if I press the area). Have googled extensively as when it first happened i was quite worried about it, but couldn't find anything to suggest it is something to worry about. It does seem to appear when I'm stressed or unwell.
