I have EDS, fibromyalgia and some arthritic joints and am in constant pain.
At one point I was addicted to opiod pain killers that my GP precribed for me. When I expressed concern to my GP about being addicted to the drugs I was told that I needed them for pain and not to worry about it. This was maybe 15 years ago.
I came off the drugs myself which was really difficult, but the opiods were plunging me into obesity and a sedentary, extremely unhealthy lifestyle that was making things worse for me and making my health worse.
I appreciate how horrendous it is being in pain all the time, however I think that habitual opiod use can make your existing problems worse, it certainly did for me.
The sedentary lifesyle and the numbing effect of the opiods was sending me into a spiral of ill health.
OP, if you can, I would advise you to try to cut down on your pain meds and to, if you possibly can, get gentle exercise, walks in nature and maybe try art, signing or anything that can help lift your mood and generate your body's natural pain relieving chemicals. Cold water swimming is excellent if you have acces to wild swimming - I appreciate that not everyone does.
I also appreciate that the current scary situation re covid may not be the best time to come off or reduce your meds. Please don't feel pressured at all.
I just wanted to let you know that, whie we are of course all different, you may find that your life and health are much improved if you are able to reduce or come off the opiod drugs.
All the best to you
