Hi
I have been experiencing strange headache like symptoms for the past few weeks. They are mild headaches , that come and go lasting only a few seconds , mostly of the left side. I have had other symptoms like pins and needles, muscle fasciculations, eyelid twitching etc sometimes.. My doctor just dismissed them as nothing. I have slighly elevated blood pressure (140/90) ..

Any ideas as to what could be going on and what approach should I take?
