What Can Cause Numbness Of Face With Nausea With Obs?

I was diagnosed with obstructive hydrocephalus about 2 weeks ago. I was admitted to hospital for obs. but discharged pending further mri scans. Now I am feeling nauseous with a numb feeling in my face. Should I seek medical advice / visit A & E, or are these minor symptoms? Kathy. 49, 5'4", 174lbs
