Discomfort in abdomen three months after liver resection/ bile duct resection.

Hello, I too had bile duct cancer and liver resection surgery in July last year.  Six months on I am still experiencing varying abdominal pains, which feels like muscle strain with a specific area feeling 'tight and knotted'.  My surgeon thinks it is nerve pain. I am currently looking into methods of pain control e.g. acupuncture or treatment via a physiotherapist.  Both of which would be private so there is a cost involved.  Does anyone have experience in these or other alternative treatments that are available.  Thank you.
