Feels like I’m sitting on a ball and Fecal Incontinence!

I have been dealing with this issue for about 3 to 4 years. It started with a feeling of a lot of pressure in my anal area, which has now moved to my vaginal area. My colonoscopy results were normal , however I did have 4 polyps, which were benign. I am still dealing with the pressure, which has gotten considerably worse! It is constant now and travels from my anal area to my vaginal area. Some mornings I wake up with feces in my underwear so I start wearing a pad every night. I now sleep in depends because I never know when it will happen. I am also dealing with bladder incontinence. I saw a Urogynecologist who suggested I try pelvic floor therapy. Needless to say it didn’t work. I saw this doctor because I thought my bladder had dropped. She said everything was fine so she referred me for therapy. My stomach is so bloated and I have lost weight over the past 4 to 5 years. My normal weight is around 145 to 150 lbs. I now weigh from 110 to 115 lbs. I look like a skeleton, to myself. I don’t know where else to turn. I am so tired of this pressure that I am at my wits end! I am either constipated or I’m experiencing diarrhea. I try to eat more so that I can gain weight, but it’s like my weight is at a standstill. Have anyone else experienced any of these symptoms? Or could someone suggest another specialist I should try? Any suggestions would be appreciated. Thanks in advance!
