My guess is placebo, done "right" homeopathy is maybe the purest form of placebo, as extreme dilution make sure that there is nothing active in there. In your case, antibiotics may have been placebo too.

For me, the most probable explanation is that your body just healed by itself and taking nothing would have had the same result. It is not uncommon for symptoms to appear, repeat a few times, and disappear completely. It happened to me countless times, like, for example a cough persisting after a cold episode, coming and going for a few weeks after I realize it is completely gone, some minor injury occasionally manifesting itself before finally disappearing completely.

Your symptoms are a bit more serious, enough for you to justify doing something, but it is probably the same idea. That your interventions worked may be a coincidence, in addition to some placebo effect which is known to be somewhat effective for pain.
