Hi.
Thanks for your query and an elucidate history.
This is very unusual presentation and needs a careful evaluation and investigations of the symptoms you have talked about.
Noted you history of loosing hearing, swelling and
tingling of the fingers and headache.
This is a serious matter.
The probable causes are:
Sympathetic over-activity.
May be some neck- cervical problems
Hemodynamic instability and so on.
I would advise you to get the following done:
- Clinical evaluation and examination and the investigations.
- Cardiac checkup
MRI of the brain, neck and
angiography of the arteries thereupon.
Anything else as suggested by the investigations and proper treatment.
Till you are diagnosed do not do so long stretches of running and never do it alone.
