Like most of us, I have more than "just" a head injury and as people like to say there is a lot wrong with me!
One of the things that have been troubling me a lot over the last 18 months is my knees. After many, many years of taking brufen and co-codamol they aren't as effective as they used to be and neither are they that good for you.
My GP suggested some pain patches, first off he suggested some Buprenorphine patches which when you look at the frequent side effects are which are significant especially for people with head injuries. I declined these.
He then prescribed Lidocaine patches, not the one you can buy in the shops with a fraction of the medicine included. These you can leave as one piece or cut to fit where you have the pain. You can only wear them for 12 hours then a 12 hour break to reapply
Wow, what a difference over a couple of days, pain is gone, more movement! What I have discovered as well, is that they are perfect for severe cluster headaches, migraine and having suffered for debilitating neck pain for years wish I had realised it was excellent for that as well.
Because it is a local anaesthetic it doesn't seem to have the effects as causing drowsiness and brain "fog" as the other strong painkillers.
Whilst it may not be suitable for everyone it may be worth considering if you have chronic pain.
