I have two sets of syptoms that I would like answeres to. One is that I have had the sensation that I have to pee really bad; but when I go I can't. Plus it burns when I do go. I also have a little sore on the lip of my vagina. I thought it was a zit but I have had it for about a month. I try to pop it and sometimes clear stuff comes out but not all the time. Plus my periods have been shorter and a lot less heavy. There is a lot of blood clumps. The other sypmtoms(unrelated to previous) I have been having are headaches about everyday that last for most of the day accompanied by neck pain in the back of my neck. I feel a pressure in the back of my head towards the middle in the top. What could be some possible reasons for these symptoms?
