A medic should come and see you after your fight. This is normal. Once adrenaline wears off you will feel your bumps and bruises. That's normal too. Congratulations, you graduated. Welcome to fight club. If you feel like rubbish, see a medic without hesitation. Don't try and man up to look big in front of your supporters, it's your health at risk when you get in the ring, not theirs. Live to fight another day and all that. If you feel bad or worried about any injury after the fight, see your Doctor or go to the NHS. Again, don't hesitate. You may know your own body but some of the more serious injuries can creep up on you without you ever realizing.
Take some food with you for after the fight, a pack of sandwiches, some crisps, a chocolate bar, etc. Make sure you drink a lot of water after your fight as you'll be dehydrated (especially in five round plus striking bouts). Energy drinks are ok too, but primarily you want water and food. Don't go straight to the bar and down several pints without hydrating. I've witnessed first hand fighters do that then go faint afterwards due to dehydration. Your constitution for alcohol will not be that high (assuming you've had a clean camp) so tread carefully.
If you're in the UK, a high percentage of amateur shows tend to be held on Sundays where venues are cheaper to rent out. If you have a good boss it is worth taking the Monday after off if required to rest up. For some it's good to have a day of reflection, feasting and resting after what's been a tough camp. For most who are competing for their first time I do recommend doing this. You won't know how you feel until after you've done it. Better to have it and not need it than need it and not have it.
Some things may scare you a little. Good. The fight game is serious business, not a schoolyard scuffle, and it should be treated as such. Train well, listen to your corner team, keep your guard up, look after yourself properly after the fight and you'll be just fine.
