My Boyfriend Got Very Bad Heat Stroke The Other Day

My boyfriend got very bad heat stroke the other day working outside in the terrible heat. He drank a lot of water but still ended up passing out, throwing up, very weak, was sweating a lot and then stopped sweating all together, his muscles in his arm, elbow, and legs started siezing up. Since then he has felt terrible still having problems with his muscles, sweating almost constantly, vomitted like black/ very dark vomit, cant pee very well or much no matter how much he drinks water. He feels like he ripped the muscles on the sides of his stomach. His penis is extremely ghost white, no sex drive, his balls are pretty sucked up to his body. He just feels awful!
