Hi, I have been experiencing headaches and light headedness and have been feeling tired easily and sleepiness and a weird feeling, and i just found this tiny lump at the back of my head, to the right, towards the bottom just above where the curve would start. And i realized that it hurts when i touch it, and well even after i touch it and remove my hand. i tried looking at it by reflecting a mirror onto the mirror but i didn t see it, well i thought i saw that area slightly red. i don t know whether to freak out or not. or whether to wait or not. this has been going on for about 2-3 days only.
