Hi Pinky,
My pain was sometimes inescapable but the most comfortable way for me to be was lying on my belly. Not very realistic way to live though.
Make sure if you take the ibuprofen that you have some food in your stomach because it can cause stomach problems. Another med I found helpful was tramadol. It is a non-narcotic pain medicine that has been around for a long time. It is prescription only. You could also ask about a small dose of valium which can help the spasms too.
I have two daughters-5 and 10. My fissure did heal up so don't give up!
