First step is to accept that you have no medical training and Google didn't provide you with a substitute ability to diagnose disease.
Everyone gets twitches, ouches, temp changes, feelings of loss of power, etc but ignores them because they consider them meaningless. You probably did previously too, but in your fear state you are over-analyzing your body looking for symptoms for Google to work on a theory with you.
If concerned about your health see a doctor which you did and nothing is wrong. If you still can't accept this, then try therapy so they can perhaps show you some different approaches to getting back to your happy life instead of futilely self-analyzing.
