Sam sorry to hear about your recent set of events.
DVT can on occasion cause swelling in other areas if a part of the clot breaks free and then clogs another vessel. For a portion of a clot to leave your leg, travel and pass through your liver and into the heart first time through the lungs back to the heart and then up the carotid artery and into the maxillary artery to your tonsil is one hell of a journey, possible but highly unlikely.
Like others have said stay the course, a biopsy is just that a biopsy...until they say it is cancer it's not...worry only weakens you and your immune system.

Talk to someone, laugh and smile and above all get some rest and Take care of you!!

e-mail me any time.

Sometimes the long climb is the most rewarding part of the journey, falling is easy. Get yourself to the top Sam.

Cheers
Mike
