Hello!
I had gone through your query and understand your concerns.
You should not think of Cancer as first option.
The lump behind you left ear might be a lipoma or a lymph node from an infection.
If the lump is hard,painless in touch and is growing it might be a serious finding and need some evaluations.
There are many possible causes for
headaches and blurry vision.
If i were your treating doctor I would first try to rule out the most common causes including:
-
High blood pressure.Measure your blood pressure 2 times a day for some days.
-
Migraine -
Sinusitis (infection of face sinuses)
-Eye problems
I suggest to consult a physician and get examined .
A detailed medical history,carefully physical examination are necessary to get to the right diagnosis.
You should run some routine tests including :
Complete blood count ,Blood sugar .
Further investigations will depend on the findings on physical examination.
You may need to do an CT scan or MRI of the head, and a biopsy of the lymph node.
You should not neglect these symptoms.Consult a physician and get examined.
Hope my answer has helped.
Take care
Dr.Rovena Murati
