Hi Missfitz,
My hubby had same chemo drug as u, also radiation, Head pain started in the front R/Side of fore head, spread down to face jaw, teeth, whole right side of head/face down to his neck,
Hot /Cold packs ease pain so slightly, new meds have let him at least get 2-4 hrs sleep now, Panadol does nothing either,
He has to watch what meds they give him, due to a heart attack 2yrs ago,
Do u massage the oil of clove on the outside of your jaw?.
Hopeful it will pass soon,
hubbby finished treatment 26th Nov 2012 too, he was treated at Melbourne ,
Thankyou for you thoughts cheers,
