When it comes to pain, ailments, diseases etc. it's mostly to do with what is behind it, the cause. And that is not physical, mostly emotional / psychological. There's always a reason why you develop something, even when it concerns an accident, diabetes, epilepsy, cracked heals, nails that break, and so on.
If you can sort that reason, you can heal. Not always 100% as damage that was created due to an ailment cannot always be undone. But the ailment itself can be healed or much alleviated.

It does require you being able to maintain the emotional / mental healing & mindset, otherwise it'll come back. That's why healing done by someone else -like Reiki- is not effective. It's like taking a paracetamol.

I've had a number of days of being totally pain-free for the first time in some 25 years in December when I started doing energy work, a specific routine each day.
I was elated, ecstatic! Finally I got joy from my body again, and NO pain!! But after a few days it came back. You really got to have the mindset and be able to maintain that, in other words: sort out the issue that's behind it.
Often we develop a disease because it makes our life easier in one way or another, however weird that may sound. Often it brings us something.
For some this could be (finally) getting some attention, for others not daring to stand tall in who they are (this is behind a great many ailments and diseases in various shapes and forms!), for others yet something else entirely.

I got a book that describes the cause of over 1300 ailments, diseases and so on.
I looked up everything that you could consider a flaw or ailment, it is all bang on.
Did the same with my ex partner, also spot on. Until one resolves these reasons and issues that are behind it, one cannot heal.

Working with Abraham Hicks and Law of Attraction can bring a lot of relief. Sometimes healing, as that is the way to go to change mindset and your energetic vibration.
Most people cannot be bothered to do that, rather suffer the pain -interesting isn't it! Another indication that there is something behind the ailment- or go see a doctor and have medication and/or surgery that oftentimes isn't necessary (sometimes it IS).

If you happen to be interested... there's tons of Abraham Hicks work on YouTube. Your healing waits for free.
Try looking for a focus wheel on health.
It's so easy, would only take some 10 mins a day of doing that, maybe a few times a day. But like I said, most can't be bothered, rather go for the pills and/or surgery.
I'm also guilty as charged, lol, not medication and surgery, but it's so easy to let go of the routine of doing it daily.
Like Abraham Hicks says sometimes: 10 minutes a day is such a high price to pay for happiness!

I'll keep at it though. Having those 3 painfree days in December proves that in the core there's nothing wrong with my body, there's no reason I should have pain every day.
I experienced it before as well btw, a few days, when someone connected me to an energetic matrix. All pain gone the second she did that. Unreal! Freakin' unreal, even for me who's experienced a lot in that area.
But again, it came back as I couldn't maintain the mindset needed for it, certainly not at the time, under a lot of stress due to relationship.
But again proof that it IS possible for me to have a painfree life without medication.
