You are not qualified, in any way, to determine what, if anything, had an effect on you or on other people. You are not capable of telling if your back pain, for example, was cured by homeopathy or had run its course. And this is why anecdotes are not considered evidence.
Anecdotes like yours are enough to warrant investigating to see if there is actually something going on. So people have - they have conducted trial and trial, and found homeopathy ineffective beyond any placebo effect.
It has no plausible mechanism by which it could work. It has no statistically significant effect when tested. It is dangerous and kills people. Hopefully you will wake up and realise this before you choose a homeopathic "remedy" for something serious and end up dead.
