I have an odd unfamiliar stinging sensation in the vagina. I read about urinary tract infections and the symptoms being a stinging or burning feeling and burning when peeing. my period is supposed to be today and when I went to the bathroom I noticed Im very faintly spotting. the pain hasn't subsided, I feel like I constantly need to pee but when I do go barely anything comes out and it stings. what do I do to make the stinging go away? is there any medication for this that would not have to be prescribed by the doctor?
