TH op asked if these were safe procedures. They have risks and side effects.
The you went into your head bleed show. This was a diversion from the original discussion
This is not a derailment of the discussion. And anyone who can read above a third grade level would realize this. I was making a point. The OP NEVER said what the MRI was for. My point is that it could be something serious that needs a scan since this could be the safest, quickest way to determine this. Sorry if that absolutely simple concept went flying way over your head. Maybe you should stick to your Dick and Jane books while the grown ups continue this discussion.
