A second opinion is a far cry from your so-called suggestions to mfreddy.
A verbal and informal second opinion is worth the paper it's written on for someone seeking answers to the cause of a devastating medical condition.
Besides what makes you think mfreddy has not already received a "second opinion?"
no mention of one - only a mystery whisper to "look into this". Not enough to hang an MD to dry out with in my opinion. Could be a disguntled nurse, a jealous colleague, etc. What happened to presumtion of innocence?
