miika, what you are describing is not foot drop. Stop diagnosing yourself, and stop googling your symptoms. This is an order.
I've said this before, to other folks who have done this, and now I guess it is your turn.
You can not earn your MD from the college of cyber-studies. Much as you try, you will never know as much as your neuro, and neither will we. Some of us might have more knowledge about bfs than the average physician, but that is simply because our symptoms bother us more than they do them, lol. Doctors are "bothered" by malignant diseases; terminal, life stealing menaces that cut people's time short and cause too much pain and suffering for a caring bystander to bear. And so, research monies, education, and study is thrown into finding cures and treatment for such things, because persons afflicted with the bad diseases are really, seriously struggling for their lives.
And here WE are, with our goofy twitches and cramps and odd feelings of weakness, and what do we do, but freak out over having a disease that we don't, and probably never WILL have? People with **S are not even as vexed or vocal about their symptoms as we are here. They are out there trying to grab what's left of their lives by the balls and stuff 90 years into 2.
So, believe your doctor, who has examined you in person, done all of your tests and declared you to be well. Trust him or her more than you trust a bunch of strangers on a message board who more than likely don't have the initials "MD" after their names.
Certainly don't trust yourself. When you researched "footdrop" online, you somehow managed to persuade yourself that you had it. Another fellow here thought he might have Myasthenia because his eyelids felt a bit droopy. And, yet another quite brilliant gal had diagnosed herself with a brain tumor, and had even convinced her doctors of her fate. None of you were correct, and none of you have **S, brain tumors, or Myasthenia.
Unless a doctor sits you down and gives you "the talk," live your life in blissful ignorance of what malady you might be suffering. It isn't as if you can do anything to change it by worrying, anyway. If that unlikely day ever comes, then you can fly into fits of panic and google to your heart's content, but...I would suspect and hope that you would find much more productive things to do with the time you had left....
Any day now, you could step outside your door and have a tragic car accident, or get electrocuted, or have a piano fall on your head. It would be idiotic to fret over any of those possibilities, and it is equally silly to worry about having a disease that, helloooo?...Pay attention here...YOU DON'T HAVE.
Blessings and hugs,
Sue
