Arthritis cannot be cured permanently or at all.
There's no cure for arthritis but treatment for arthritis and medicines can help ease the pain and symptoms of arthritis but as of now there's no cure for arthritis.
As long as you continue to treat the arthritis and take pain medicines for the arthritis you can make the arthritis pain go away and keep it away.
But once you stop taking the pain medicine for the arthritis and cease treatments for the arthritis then the arthritis pain will come back.
Once you get arthritis though it won't ever fully go away but you can ease the symptoms.
