The Implanted Defib in my chest is trying to eject itself through the skin.
Whether this is the body rejecting the thing or corrosion of the electrical leads they will be seeking to discover. Whichever it is they will, at some point in the next week or so, have to replace it. Replacing the defib is relatively simple but changing the leads is a tad more difficult and dangerous as the latter involves inserting an electrical cable through the heart itself.
I am not looking forward to the verdict.
Meanwhile I still await the recall to have the rest of the cancer tumours removed.
