Hello. On Wednesday afternoon I hit the top of my head hard on a metal AED cabinet with rounded edges after relocating a basket under it then lifting my head up (I didn't see the cabinet - I wear glasses and it was a poorly lit area). The pain was very sharp and I applied an ice pack and took paracetomol. The pain was consistent with a feeling of heaviness spreading over the top on my head. I still have pain in my head and it still feels heavy on top. I have Menieres so it is difficult to know whether my 'dizziness' is associated with my injury or my existent medical condition. I am finding I am needing to concentrate harder when writing and speaking. How long should I wait before seeking medical attention? I live alone.
