I am also dealing with multiple problems starting with juvenile arthritis since my teens to the latest four surgeries where part of my colon removed and I got sepsis and almost died.
I was addicted to opioids for 9 months but had the support of my caring doctor who went on writing me lessening prescriptions as I weaned myself off using various CBD products. I went through a dozen tinctures until I tried Tommy Chong's day & night formulas. They use nano technologies and work well. A little spendy but once you are on the mailing list he has frequent 30% off sales and I stock up then.
I also use a cream/lotion from Nightingale in Portland, OR. This is a great combination of CBD, no THC but also has MSM and about a dozen pain soothing herbs. Nightingale Remedies CBD. Also spendy but try one and if it works for you there are discounts for buying 3 or 6 at a time.
I've tried a lot of gummies and my favorites are from Gron.(Supposed to have an umlaut over the "o" but don't know how to do that on this keyboard.) They make gummies in varying flavors with varying amounts of THC--I use the pomegranate one. These are not expensive. What I've read is CBD works better with a little THC included and that seems true for me.
I'm not a medical practitioner, just a patient, so I am only saying what works for me after a lot of experiments. I only use the gummies when I am really bad, but use the tinctures and lotion every day. Takes about 4 or 5 pumps on each joint that is aching and rub it in good.
Don't know where you live but hope you can find these and they help.
