Had 2 metal plates and @ 15 screws to fix ulna after serious fall. ray shows all has heal well, no arthritis, but metal plate is so close to skin I have develop like a fluid pouch in area that constantly gets hit while normal use of arm ( while typing, driving, washing dishes, etc). Sometimes it gives burning sensation. I have regain full movement and strength and have a beautiful small discreet scar no scar tissue. Should I have metal plates removed?
