Before going the surgery route, try going to Wal-Mart or a pet store and purchase a bag of Instant Ocean(it is a sea salt, people use for salt water tanks). Put liberal amount in bath tub with warm water and stir..take a sitz bath(enough water to sit in) for about 30 minutes at time.(read a book and relax). Depending on the intensity of cyst or boil should start leaking out shortly after leaving bath. Will be gross and foul smelling, but gone! Instant relief! Take a shower and smile!
I have been through the same routine as you-down to the delivery of my second child with a huge cyst right there. I have had numerous drs. telling the same thing as they told you...not knowing what it is..I finally had a O.B. that told me to do this and it works! Unfortunately, it will come back, but a good indicator when there is an infection somewhere in your body.I know it is painful, but hopefully, this will be a remedy for you as well as it has been for me numerous times!
