Thank you for posting your query.
It is difficult to come to a definite diagnosis without clinical examination.
However, the likely possibilities could be a brain stroke
or cervical disc disease
In brain stroke, the blood supply to a part of brain reduces, resulting into heaviness, numbness
or weakness of arm or leg.
In cervical disc disease, the nerves emerging from the neck region, which travels to arms, gets compressed due to the bulging of discs in the neck region. This can cause pain, tingling
, numbness and weakness of the arm.
I suggest you to consult a neurologist
for a definite diagnosis.
Wishing you good health,
