For a week, my eyebrow area have been feeling quite strained and I usually have a clear complexion, not sure if it is related, but I have been getting pimples (non-pus ones) on the left side of my face. I can move my eyebrows and there is no pain, my eyebrow area (forehead area where it gathers when you frown) just feels really stiff and strained. It is an uncomfortable feeling, almost like I an eye strain. (I have a long hour desk job). What could be the problem that is causing this?
