<human>: 18/M/Phoenix 5'9

I posted here about a week ago about a hypoglycemic episode that led to fainting. I've never had this problem before, and while my symptoms are slowly improving, I've been experiencing a bit of vertigo since I fainted and hit my head. 

EMS and ER both ruled out a concussion, but on Wednesday I started to feel very nauseous (no fainting) for about 30 minutes before I went to the on-campus clinic, where they ordered a bunch of tests from a different ER (blood/urine/EKG/chest X-ray), all tests came back good to go (trying to determine the cause of fainting, which I believe was heat exhaustion). 

Only difference was both this ER and clinic diagnosed me with a mild concussion. I've been given a scoresheet to track my symptoms (score was 18 on Wednesday, around 6-7 most of today). I didn't complain of a headache so no CT scans were ran. 

I've been noticing that when I overeat, I'm way more susceptible to nausea and dizziness than before the fall. I am still sensitive to heat as well despite increased efforts to hydrate. 

I didn't develop a headache until 6 days after the fall, but this was also after blood tests. I woke up with a very slight one this morning, but slept through the night for the most part. 

I guess what I'm trying to say is that aside from vertigo, I feel perfectly fine. I still feel a little out of it (ice cream helped somehow), but the vertigo stays and it's my main debilitation with my recent symptoms. Is this any concern or was the concussion so minor that I just have these weird symptoms sticking around but not a lot of common symptoms?

No sensitivity to noises or lights, no fever, barely any headaches at all, no sleeplessness, no personality changes. Just vertigo. 

**I should also note that I do have a follow up for a fasting glucose test on Wednesday at the clinic and maybe a hemoglobin a1C test. Following up with a nutritionist 2 weeks from Wednesday as well. I have been regularly in the doctor's office for monitoring.

Condense the text into a few key points
<bot>: I'm very responsive, only one headache related to blood tests and not the concussion, felt fine 5 days after the accident and then felt symptoms again, currently only dealing with slight vertigo mainly after eating (now 8 days later).
