Hi Peter I too have T2 and COPD but thankfully quite mild but I also have Bronchiectasis and Spondylitis of the lower spine which gives me chronic pain in my right leg. What meds do you take for your copd and spondylitis, its always good to swap tips.
I use various inhalers for the copd and bronchiectasis and have been through just about every pain killer from paracetamol to DF118 Codeine for my arthritis, I now use Transtec™ Bupronorphine slow release patches which have been a game changer for me although I still do get breakthrough pain occasionally for which I take just paracetamol and or ibuprofen, I also wear Cura-Heat™ 24 hour patches on my lower back if I get pain and or swelling there, I find them useful too although I do pay for those as I dont think they are available on prescription.
