if your brother has had a trauma in his anus or perineum area or suffered a major fall, my humble and personal experience is that his tendons in that area are ¨frozen¨or have suffered a trauma and are not allowing the free movement of the muscles said tendons are attached to. i was also diagnose with hereditary spastic paraplegia 18 years ago and told i would never walk again. when i was a child, i suffered a major injury to my perineum. it was by healing the perineum, the anal ring and the perineal membrane that i was able to heal myself. good luck.
I am recently diagnosed with Pudendal Neuralgia. So here are my symptoms..
Groin is burning 90% of the time.
Sitting causes extreme burning on my testicles and penis.
laying down can cause burning, but sitting is the worst.
I have terrible back pain and I do not know if is related.
Sex is very painful due to burning when its over.
Masturbation is out of the question.
Friction is extremely painful.
It is quite maddening. I am seeking help from a staff at a local university's neurology department and have an appointment soon.
So, far to come to the conclusion of this problem, it took 43 doctors because I had to be seen at grand rounds. The head of the dermitalogical board at this university had me go to grand rounds to nail down what it was. He theorized it but wanted to make sure.
It has been a slow proces.
I have an appointment with a pain clinic too which may help. Your brother should look into a pain clinic.
Hi
Pudendal neuralgia usually presents with pain when sitting down or lying down. Diagnosis may be elusive as this may be misdiagnosed most of the time. Several factors appear to contribute to your brother's symptoms .This includes his previous surgeries, his neurological problem and a possible underlying surgical complication. Neurological deficits may cause neuralgia as part of the disease condition. Pudendal neuralgia may be a differential here but this pain readily involves pain in the groin and the anal regions. If this is consistent to your brother's case, an EMG may be done to determine involvement of the pudendal nerve.
