fullness in the right side of my head with numbness
Probably stroke, go to ER.
Hello dear, welcome to Ask a doctor service.
I read your query and here is my advice.
I think the facial numbness in one side of head, fullness and imbalance may be signs of stroke. Also if this happened suddenly and for first time most probably is sign of stroke (poor blood flow in brain).
I think you should seek medical attention soon. Go to ER immediately to get evaluated and get help.
Hope I have answered the question.
Let me know if I can assist you further.
