Once during camping, I got an extremely bad charlie's horse/hamstring cramp/howeveryouwanttoput it. It's where it feels like someone is basically taking a screwdriver, jamming it into your hamstrings, and twisting it all around, and having it pulsating. It was the middle of the night, and I tried my best not to scream.
That and one time, due to a wisdom tooth infection, I had extremely sharp pains when swallowing. That lasted for 3 days, and I swallowed frequently due to me having a lot of saliva.
Grade 9 gym class. Through some seriously stupid amount of luck and some people's lack of spacial sense, 2/3rds of my body react to getting slammed into by those thick 'exercise mats' (because someone was so nice to have been not paying attention while I was helping them move it) and instead of "Oh, ow, hahaha" I ended up with this supercramp, and a couple of my muscles (not my whole body, things like my forearms and calves, neck and legs, even my left wrist) contracted for +/- 2 minutes.
You know when seconds before you accidentally pull a muscle, you almost know you're going to do that awkward movement? That palpable sensation of "Oh, f***, here it comes"? I pretty much went to try to stop myself from falling (both away from the MOVING WALL OF BLUE and myself towards the floor) and felt that brief sense of numbness before I just locked up and fell.
It hurt like hell, and I kept (stupidly) trying to move but all I could do was see 1 or 2 fingers flex, my arm jolt slightly and feel this... incredible constrictive, restraining, burning, tensile force. The right side of my abs made it feel like I was suffocating and I kept trying to arch my back and flip myself over because I felt so helpless.
Someone asked if "I could get up". My thighs couldn't move my legs, how the fuck do I get up?
After they 'let go of themselves' I literally couldn't even -stand- up, or hold something without feeling like my limbs were made of gelatin.
Then after I had a couple sprained joints that I had to deal with for the next few months as well as some medical asdf.
always drink your water and stretch before exerting yourself kids
