Peppermint oil on your temples (if you don't have a skin sensitivity to it).
Ice pack on the back of your neck
Don't know what brand oils you use but several have headache blends. Young living has M-graine and wydmere naturals has head-aide... just check to be sure they don't interact with any of your meds if you plan on using them on your skin. I use them in defusers.
I use rescue remedy lotion, it is one of the Bach flower thingies
a lot of things that work for migraines work for tension headaches too
There is a pressure point on your hands between your thumb and pointer finger, working on the knot in the muscle there can help.
If back problems are contributing anything to help the back problem will help the headaches. I have neck problems that will trigger mine and I use Tiger Balm (similar to Icy Hot)
Just be sure to check with your Dr too. The headaches can be signs of other health issues and you want to be sure none of the things you do for your headaches interfere with any meds you may already be taking.
