Noticed and felt a small pimple in inner labia region (right side). It is not painful when touched but I feel it is growing everyday. I am also having trouble sitting and getting up/moving from one posture to another because of a sharp pain near inner thigh and the entire genital area. I am in my 34th week of pregnancy and when I discussed that I have a sharp pain and pressure like symptoms in the lower abdomen, my doctor also suggested that it could be due to the fetal pressure being created in the lower pelvis region. Now I am wondering if it is this pimple which is causing me all the trouble. Please help.
