They are called vaginal fissures and r so painful!. I have had a problem with these for years ( like 10 years plus) long before I got pregnant. They would appear completely randomly for no reason. I always get them in the same place to the point I have scars now. After having both kids I ended up with one long one that was almost 4 cm long and only about 1/2 mm thick - like a paper cut - that would not heal, it developed a few weeks after their births. I saw the Dr for that and she said try a 0.05 % hydrocortisone cream very sparingly to help the skin heal. Whst happens is the skin can't heal and the skin keeps splitting in the same spot, making it weaker, so it splits again. It's like a vicious cycle. I only use the cream if they are really bad now and it often only takes 1-2 days to heal. If u google vaginal fissures you'll get a lot more info. Oh and with pawpaw, be careful as the sugar in it can bring on thrush or if u get some kind of infection in the fissure the sugar can feed the infection.
