I dont know if it will help, but my breast care nurse advised 1 maxalon plus 2 panadol for the big post chemo headache. Works for some not all. Worked for me. Wish I know about it on round 1!. Love arrowroot biscuits. Green tea with a slice of ginger. Apple cider vinegar (weak) with teaspoon of honey. Ice pack on head or face flannel that was popped in the freezer resolved the head itch as did a massage with olive oil. For some humour check out headcovers.com. A USA cancer website. I bought some "caps" which are really light and fit under my beanies and hats so no irritation. My sister in law bought me the multi colour floral swim cap for summer when my radiation is finished. Very 1950's. Laughed so had when it arrived in the post. Also check out the hats with hair much laughter there. I'm thinking denim hat with plaits for a treat.
Take care.
