Injury has no definite relation to brain tumours.
You seem to have posted this question almost a day ago. It's a rare occasion where a query is not answered for so long on this website. Perhaps lack of sufficient information and slight complexity of your questions might have discouraged doctors here. I shall try my best to provide you with some related information.
At the outset, I am glad you recovered well after a serious head injury
. Besides this pain you seem to be doing good. Many people suffer from post traumatic disorder that are more severe than yours.
Coming back to your post, I don't find significant differences between a bad head pain and headache; maybe you have localised severe pain and not a generalised headache. And as previous doctor mentioned it may be from the scarring. As it is not worth the risk to undergo a second surgery to treat scarring just to reduce pain, I would have treated you with pain controlling medicines such as carbamazepine
, gabapentine, pregabalin, amitriptyline
and many more. There are numerous medicines that lower pain threshold and eases pain, I am not sure if you have tried those. If not please discuss with the doctor.
With this little information, let me answer your questions:
1. Neuroma is a benign harmless tumour that arise from nerve tissue. Though they can occur almost in any nerve cell, it commonly presents as lumps on limbs and body. Internally abdomen and thorax are common areas. Within the skull this tumour is commonly associated with 8th cranial nerve
where it is referred to as acoustic neuroma
. But I don't think acoustic neuroma is associated with head injury.
2. Acoustic neuroma commonly presents as dizziness/vertigo, hearing impairment
, ringing sensation of ear and balance issue. Pain within the skull is not the typical feature. Neuroma of other brain tissue / nerve is rarely found. If found it would present like any other tumour - pain and increased possibility of seizure. Therefore though your pain may be related to neuroma, it is a very remote possibility.
3. As I said earlier there are various medicine that increase pain threshold. I have listed the most common medicines above; I am sure one of those should help you.
4. There are various articles and research publications on the web about neuroma, acoustic neuroma and brain tumour. But based on the details you provided, I think this short publication would suit your need:
I have listed various aspects about your condition. If you wish to know anything more specific let me know in the follow up, I'll try my best to help you.
