Hi, today I was running from the parking lot to the sidewalk and I fell, face forward and I landed on my knees and stomach. I got up, looked at my knees and saw some scrapes and kept walking thinking I was fine even though it hurt. I walked for a bit and while standing in line, (probably less than 10-15 after falling) I felt my left knee hurting quite a bit and I could feel it against my jeans as I was standing in line. I looked again when I went to the restroom and my knee was swollen and a little bloody. I got home about an hour later and cleaned it up, out some antibiotic ointment and took acetaminophen because my head was hurting quite a bit, even though I did not hit my head anywhere. I did feel a little disoriented right after I fell, but I didn t think much of it. I was just embarrassed. My headache got worse but I thought it was because I was hungry. after a while the headache started fading, but never completely going away. I ate after a while. My headache started feeling bad again and I have been feeling nauseous, I do not know if it is related or not. I cleaned up the wound again and took some more acetaminophen because my head is hurting like it was earlier. I fell at about 2:15pm and it is now 11:08pm. Is there anything else I should be doing?
