UPDATE: As per a couple of suggestions I received, the list that appears below is now available as a 1-page PDF download. Please press the blue button to download this list:
For example, #27 is for wild animals and #118 facilitates giving an answer to an apikorus (a heretic). There are also quite a few that apply to specific ailments, both mental and physical.
With a lot of people suffering from minor to major ailments, it might be nice to know which perek (chapter) can be said for a specific ailment.
Note: The translation for kedachat isn't clear to me. I've seen it translated as "fever" or "malaria." To complicate things, the index calls different ailments kedachat revi'it (fourth fever/malaria) and so on. So I'm just leaving it as kedachat below.
If you know for sure, I'll hope you'll either send an email or leave the definition in the comments!
Also, there's a perek you say for the left leg/foot, but I didn't find anything for the right leg/foot. So I suppose you could just say 119:145-152 (kuf) for both. It can only help.
Unfortunately, I didn't see any for respiratory issues. (Or maybe that could be included in kedachat? Well, it can't hurt!)
Anyway, here's the list:
3 -- for shoulder pain and head pain
