Ob-Gyn questions? Ask a gynecologist online.
if the symptoms continue or even are getting worse, it can´t be only a small injury, an infection then is much more likely. So I would recommend a check-up by your OB/GYN, treatment then depends on the result.
Hope you get well soon, please don´t forget to honour my work with a kindly rating (3-5 stars).Thanks a lot, all the best for you,Dr. N. Scheufele
