Yeah I'm fine now.
I play a bit of over 35s football to try and keep fit. Was playing in nets and got the ball at full pelt in the face, went straight over backwards and cracked my skull on the hard earth. Have never felt like my brain was spinning in my skull before, wasn't nice. Felt sick and dizzy all evening, and still have a mild headache now and I am having a bit of trouble concentrating ( maybe I always have and only noticing it now )
Cheers for all your concern.
