I'm Shady and I'm a 15 year old male and was just diagnosed with concussion

On August 2nd I was playing basketball with friends and I rammed my head against another kids head

What sucks other than having a concussion is that I didn't feel anything other than a headache for 4 days and didn't rest because I didn't know

This isn't my first concussion and I had my first concussion when I was 4
