Can you tell us a little about the implants you have, and why they need to be removed?
Also, yes, it is concerning. But the very good news is that once the metal implants are removed, your body begins to eliminate the cobalt and chromium all by itself. Within 6 months to a year it will be back to normal.

Whether you have any permanent issues from it probably depends on how long the implants have been shedding metal, and how severely. The records that showed my pre-surgery metal leves are no longer available, but the numbers were much higher than yours, and I have recovered with minimal long-term effects.
