Thanks for using the forum. I am happy to address your questions, and my answer will be based on the information you provided here. Please make sure you recognize that this forum is for educational purposes only, and it does not substitute for a formal office visit with your doctor.

Without the ability to examine you and obtain a history, I can not tell you what the exact cause of your symptoms is. However I will try to provide you with some useful information.

It sounds like you have several symptoms that are difficult to tie together into one diagnosis. Ringing in the ears (medically known as tinnitus) can have many causes including prior exposure to loud noises, hearing loss, and other ear-related (non-neurologic problems). Tinnitus can also occur with benign brain tumors called schwanomas which frequent occur in a specific brain area (also known as acoustic schwanommas). If by dizziness you mean room-spinning, this would also occur with these types of tumors and a brain MRI may be indicated to exclude this (depending on your exact symptoms). If by dizziness you mean light-headedness, there are several potential causes, but often this is due simply to dehydration, low blood pressure, etc.

Fatigue and generalized weakness have many causes. A sleep disorder such as obstructive sleep apnea needs to be excluded, particularly if you are over weight or snore, as this can cause daytime sleepiness. Thyroid problems, anemia, and depression are other causes of fatigue and weakness.

I recommend continued follow-up with your physician for your symptoms, with evaluation by an ENT if your ear ringing persists.

Thank you for this opportunity to answer your questions, I hope you find the information I have provided useful, good luck.
