shaking

Hi, didnt know where to post, since no one has any ideas about what i have.  started biaxin xl after strep throat, then i started shaking.  not very visible, but very slight, and it's constant.  got off the medicine but am still shaking, it's been two years now of constant shaking.  the doctors tested everything, got nothing.  high blood pressure started, six months after the shaking, on atenenol now.  started getting different than usual headaches in november.  on top, left side, near the front, and back parts of my head.  they've moved to more and more constant.  speech and language changes.  a little dyslexia with numbers started.  a little apraxia of speech, not a lot, but i'd say a few times a day.  then, in writing, i guess it's anomia, not sure, i started writing the wrong word than i intended to use.  completely, unreleated word.  i was tested for ms, limes, adrenal gland tumor, hmmm, cant remember what else.  the doctors basically gave up, but im getting more worried, cuz of the headaches, and speech changes.  thanks.
