Since you have a headache and twitching, perhaps you should see a doctor and get an X-ray or ct scan to determine if you are hurt worse than you think.
You probably have a concussion - and usually they are not bad enough to warrant medical attention. But sometimes a concussion can cause a bleed in the brain or a crushed disc or cracked vertebrae.
If you can afford it, go to the ER and have them check you over.
You log the injury into the works Accident and Report Book if you have done this.
Make an appointment to see your doctor straight away. I think that you go to A+E within 24 hours of an injury. If symptoms do get worse, make get someone to take you to A+E
As you are in the UK you can telephone your doctors telephone number any time after your surgery is closed and you will be transferred to the out-of-hours doctors, they will give you advice.
You may in fact have a slight concussion...and possible whip lash.wouldnt hurt to seek medical attention. not sure how much a roll of banding weighs but I would not just leave it..you may have nerves from your cervical spine swollen or muscle so it could also be inflammation.if you don't want to see a dr, go to a chiropractor..!
It is free for people to go to A&E in the UK. This is for emergencies only and not for routine problems. The problem is these days that some hospital A&E departments close in the evenings and open again the mornings due to lack of funding. So it really depends which town you live in.
I was just now reading an article on a young fella who suffered a severe head injury - not expected to survive. His family and a friendly doctor put him on large doses of Omega 3 (fish oil ) and he made a complete recovery!!
Just saying... it can't hurt.
