Hi there. About 30 hours ago now, I was hit in the chin with a basketball really hard. I felt my head rattle in an unnatural way, and pain in my head. I brushed it off and kept playing for about 15 more minutes. When I got home, I felt pain in the front of my head, I felt a bit weak and disoriented. I slept a few hours later, for 8 hours, woke myself up every three to two hours. My symptoms now are fatigue, slight disorientation, and most recently, stomach pains, almost like cramps. I didn t go to the hospital, so I d like to know what else I should do to help myself?
Cannot say in your particular case. Certainly signs of concussion include headache, disorientation, fatigue, wanting to with Chat Doctor.  Concussions last at least hours and more likely days. There is increased risk for SERIOUS consequences if further injuries occur DURING a concussion and so, rest and avoiding further risk of concussions is strongly advised. But, this isn't irritation of the stomach. That can certainly occur with any stress. And in this case minor treatments like antacids are somewhat helpful.
