I have same dull ache, on and off, from left wrist to joint, around left shoulder blade, left ear to the head area, and I can feel a mild tension to my left eye.
The ache can last 2-3 days, and usually attacks 2-3 times in a month.
I want to share you all, traditional way that you can do it yourself at home (at your own risk of course).
In Indonesia, it is believed that bad wind can obstruct / block blood circulation and causing pains (including dull pains). So, a practice of "kerokan" (you can browse in the web), is every day cure in the country. Honestly, for me, when panadol didn't help, this approach is helpful to alleviate major pains I experience.
What you need just any type of oil (can be vegie oil) or balm, and a round coin with smooth edges. Find the areas where you feel the pains, rub with the oil, and scratch it. When the areas turn red (after being scratch), it is believed that the wind has gone.
Hope this helps.
Try "Kerokan". Browse "kerokan" in the internet. I use this method when the pain hits. Usually, I start with my shoulder blade. You need oil / balm and a clean round coin with smooth edges.
-Thanks
