I am dealing with arthritis, the normal kind, and gout related arthritis, which also ties into my diabetes.
If I were you, I would get a blood glucose monitor and see where your blood sugar levels are during the day, a lot of test makes me need more insulin. I am type 2, and both my parents are, and I fought it hard.
The way I cruise is ad a little deca, 150 mgs a week, is enough to take care of a lot of my arthritis.
You will be on supplemental testosterone for the rest of your life, there is no getting around this unless you want to live like an old eunic.
I need to give blood myself, but that is one of the better things for all the extra iron. I just hate doing it.
Good luck man, and relax, the damage is already done, and now you just have to recover what you can, and figure out what is really going on
