Head trauma remedies

Hi guys, long story short, was doing MMA/boxing ( im 130lbs, my opponent 160 ), I jabbed, I missed, he jabbed and punch me in the head super hard. I wasnt k.o, but I felt my head my brain move and saw a white flash. We continued but very lightly after that to avoid any more injuries, but the next day, I still felt my brain was throbbing. Asked the coach what to do and he told me to take some advil and no sparring for 2 weeks. Does every boxer go through this? Whats are your remedies/tips? ( Only been doing mma for 2 weeks ). Thx for the help!
