Don't bottle it mate. I am/was a student aswell and as such couldn't afford to go the private route. I went to see my Doctor on campus because of a cold and then brought it up just before leaving - was close to not saying anything. I explained to her that it was affecting my life seriously, not swimming because can't take off shirt etc.. I asked her if I could get surgery for it on NHS and she wasn't sure. Next thing I know is that I have a letter saying I have a consultation with a surgeon at the local hospital, went to see him was there for 5 mins and he said yeah you have it and I will do the surgery. Six months later and I have just had my surgery on the NHS. I was very close to walking out at every single stage, even while waiting in the hospital. Don't quit now mate, the worst they can do is say no but then atleast you will know.
Good Luck
