From the bottom of my heart, I am so sorry that you are experiencing all of this while pregnant!! I just had my baby 3 months ago and my issues happened after my c-section surgery. (Lots of hard BM)..anyways, I have read tons of times about how people get their tags removed and they either end up with problems or new ones form. So with your new one forming, it doesn't sound unusual. Yes you can re tear your fissure and it does sound like that's what's happened. Are your stools bulky? I would stay away from eating too much fiber and try just drinking tons of water, eat fruits and veggies of course and stay on the stool softeners. Ask your doctor if you can take miralax. It works wonders!! For me, I think the healing of my fissure started when I was taking miralax, doing sitz baths and then I'd use a coconut oil suppository. (Made them myself). I can't explain why it helped but The coconut oil, when inserted as a suppository, it brought my pain level from 10 to a 2-3 basically not being able to walk, to being able to walk just fine! I don't know why it helps so much but I've been recommending to anyone on here to try it. It's 100% natural so it won't harm your baby. I would love to be able to help you and others lessen your pain by trying this. Please take care. Again, I really feel for you and I hope this is just a minor setback and that you'll be feeling much better soon!!
