What Causes Swelling And Pain On Left Eyebrow After A Injury On Left Temple?

I fell and hit around/on my left temple on concrete 3 months ago and it is still swollen and have little to no movement on my left eyebrow area. Randomly I get sharp, burning, and ripping sensation (the feeling of pulling scabs) and have to lightly rub it to get the pain to be bearable. It also hurts when i press lightly at the start of eyebrows. Got two ct scans and came out normal so primary doctor told me to jus check in monthly.but honestly all this happening doesn t feel normal. I may be causing more pain upon myself since i have a lot going on in my life and couldnt put my life on hold after a month since this happened. With this situation and everything going on i am having stress overload, where my period became really irregular. Past 3 cycles (within 2 months) have been about a week apart and last cycle lasted 22/23 days. I still have hard time sleeping, concentrating, remembering and vision got worst . This is my first serious concussion (head to concrete, before was head to grass from playing sports) and really don t know what to do or who to seek. Hope to get some answers. Thank you for your time.
