Thanks a lot for wanting to share your own story with me! And adding all the things that might help me since they helped you! :-)
I've certainly looked into diet as well. Actually, the thing that helps me, since arthrosis falls under the auto-immune illnesses like rheuma, is lowering my refined grains and sugar intake. So basically I've not eaten ANY grains for months, this seemed to help within 2 weeks, and after that I started eating 'some' grains again, but it's not a stock in my house anymore and don't miss it at all.
Also: add kurkuma, more vitamin D in the form of cod fish oil, more Omega 3 (salmon, yummm) and less Omega 6 (which is in a lot of oils). This all lowers your auto-immune response, which helped me with the pain AND as a bonus I noticed I'm not on a suger drive anymore, so I'm never hungry! (I used to need food every 2 hours, but I eat more proteins now and feel AMAZING, no 'blood sugar collapses' anymore!)
I'll look into some of your suggestions as well, I learned food is an amazing medicine :-)
Good luck on your own physical discomforts as well! Wish you all the best and health!
