Hey Gi231,
I'm assuming that the main source of your pain is the fissure, and that the hemorrhoids are secondary.
I think the most important thing is to get some healing going. As for pain, I've found that it's important to stay ahead of the pain. When my pain was at its worst, I would take 600mg Ibuprofen about one hour BEFORE going to bathroom, and then another 600mg about 6 hours later.
I know the medications you're using are supposed to be helpful, but it seems that they wouldn't be very helpful unless you also make other changes. Here's what worked for me:
1. Switch to high fiber diet.
2. LOTS of water. Especially at night. I drink lots of water before bed, and I also wake up several times at night and chug even more water.
3. Gummy Fibers, I take 6 to 8 of these every day, all before 3PM:

Now, I go whenever I need to go. I really think it's far better to have several smaller BM's than it is to have one really big BM. I can't stress this enough. In the past my BM's were really huge, and all that stretching and trauma was far worse than what several smaller BM's would have been.
Basically, what you want to do is to convert your body into a "soppy water drenched sponge" so that everything inside passes right on through with minimal trauma.
