Burning sensation in birth canal for the past 2 months i'm 2 weeks and 1 say till due date feels like fire poked deated to branding iron temp.

Please see physician: You may need urine test to rule out urinary infection or any local cause for burning sensation. Please talk to your obstetrician

Vaginal pain: Its not uncommon to had sharp vaginal pains in the last few weeks before delivery. However, that doesn't mean you couldn't have a yeast infection, herpes or some other vaginal infection. Probably a good idea to have your OB provider do an evaluation just to make sure you don't have one of these issues. If tylenol (acetaminophen) and rest relieves your symptoms its more likely pelvic stretching.
