Hi @shann, I have been following your posts and wishing all will heal but it doesn't seem to be healing right. I am thinking autoimmune disease as well and found 3 links which may help. You would need to see an oncologist and maybe to get it via pbs system, lie a little by your doctors and say its arthritis treatment? Just trying to think outside the box. <3
