Hello. I've been feeling light headed, weak and dizzy, light and sound sensitive, and feeling kinda stiff in my face and neck at times with a strange subtle headache of such for about a week. Now the symptoms have subsided significantly, but I still feel that subtle discomforting headache particularly at the back of my head, it tends to roam all over though. And also I have a history of having these really sharp intense pains in my head that last for a second. Now my body feels hot but no fever
