Hi again Sean,
I hope you get a consultation with another doctor for a second opinion asap.

Some of the symptoms you describe on your other thread are concerning as well. To be more specific, they are your bouts of rapid heart beats, chest pains, breathlessness etc.. It concerns me that some (or all) of these other signs and symptoms you described could be contributing to your head pain issues (or vise versa) and not necessarily separate conditions.
