Son has spastic quad and autism - head hitting

lindscunane

My son has spastic quad plus autism. He is a lovely placid 15year old. He deals with change etc very well. Just over a year ago he started out of the blue hitting/punching himself in the face and ears. 
After months and numerous visits to the hospital (Alex looked like he had been beaten up) they diagnosed Sinusitis. The behavioural stopped as this was treated.however, a few months later it started again but his sinuses were clear.... to cut a long story short after an abdominal x-ray we found A was impacted and severely constipated. 
We have been dealing with this, however, this time the head hitting mainly at bedtime isn’t subsiding. 
He is waking at 2am and hitting himself.. causing damage to his face and ears. 
We have been giving him a sedation to try to help but makes little difference. 
Everyone is saying the behaviour is due to the pain from the constipation but I’m not sure now as it seems to be going on too long.
I am exhausted and just want the old A back.
any advice would be appreciated. 
I have spoken to several medical professionals and CAHMS who have said his behavioural wouldn’t just change and it must be associated with pain. 
Thanks in advance.

Hi @lindscunane

I'm so sorry to hear about what you're both going through, and hopefully our parenting advisor will be able to offer advice soon. Have you had a look at if any of our advice on challenging behaviour might help?

Hi @lindscunane
Welcome to the community, I am so sorry to hear about your sons struggles.  If they think this is down to pain, are they doing anything to deal with this pain?

Constipation and impaction can cause issues for a long time and sometimes once the bowel gets extended it can cause continuing problems.  

It must be really difficult for you all to deal with,
