Some options include:
Get tested to to see if there is chromium or cobalt still in your body.
Get all of your thyroid hormones checked ( heavy metals can affect it.)
Get your heart checked. (I developed a permanent rapid heartbeat and slight arrhythmia from the metals or thyroid.)

My gut issues turned out not to be from the metal, but instead a very sluggish and inflamed gall bladder (for years.) Once removed I feel better than for a long time.

Keep pursuing a solution.
Have you had metals and thyroid checked?
