Disclaimer: I am not a doctor or burn expert of any sort.  I am an extra class ham.  An RF burn will penetrate more deeply than a &quot;conventional&quot; burn of similar degree, possibly burning nerve cells, circulatory and other structures that an external burn would not.  RF burns typically heal very slowly.<p>I can&#x27;t compare RF burns to burns caused by electrical current, except to say that electrical current will follow some path of least resistance while RF energy will heat flesh in a pattern corresponding to the field of the radiator and the impedance of the whatever matter absorbs it, so these types of burns will have different patterns.
