Massage therapy with scar tissue work can be done from the outside of your body.
Ask a massage professional if they are familiar with this type of work. After you have had a few sessions you can learn to do it yourself with lots relief...
Have you had this pain since you surgery or did it start after? I could be a pinched nerve causing sciatic pain. You should see your Dr to rule out any problems from your surgery and if everything is alright you may want to see a Chiropractor. Take care. Remar
