Hello, so I was in chronic pain with osteoarthritis for 2.5 years until I had my hip replaced. I am having my second in a few weeks.
You can try cortisone shots in your hips. (You will need someone to drive you to and from the appointment).
You can do physio from YouTube - you need to strengthen your glutes. It’s not going to do anything for the bone on bone pain but you have to keep your muscles working.
You have to do something concrete about your weight as you know. You can join weight watchers online and get your food delivered via Ocado so you plan your meals and only get what you need.
Swimming - even walking in the pool will support your joints and may ease some of the muscles that tense up from being in a lot of pain.
I was on codine, naproxen every day for months and hated it!! I rate Paramol which is over the counter but with all these they cause fuzzy heads and are awful.
If your lower back troubles you I used a tens machine that I got off Amazon. I don’t really remember how much good it did but it felt like I was doing something.
Counter intuitively I found spin classes and being on an exercise bike helped. Something about getting the blood flowing.
I didn’t do this but medical cannabis can really help ease pain for some people.
The NHS has a pain clinic- I didn’t do this either but I think it gives you mindfulness and mental strategies to deal with chronic pain.
I have given you a lot and others have given you ideas. Make a list and then make a plan. It’s not over yet. There is still things you can do and things can get better.
