Strange discomfort at bottom of vagina

I just got over what was diagnosed as a very severe yeast infection, that caused a bad rash between my legs and lower vaginal lips, and between my buttocks. Now that the rash and the pain has 90% gone, I've noticed a strange 'hard' discomfort right at the very bottom of the vagina just between the folds, just above where it and the buttocks connect. It's not very painful, just has the strange uncomfortable feeling like it's very hard or there's a small lump between there when I walk, sitting down is fine. Have checked and there's no hard skin or lump, but a little thick, yellow white discharge. Is it just this part of the area taking it's time to heal from the infection, and nothing I should worry about? Or is there another cause of this? When I put my prescribed cream on twice daily (Lotriderm cream: part clotrimazole and part bethamethasone dipropionate), I include this area. Has this occurred because I was not supposed to touch that part? Any help would be great, thanks!
