I really don’t get it .. this pain started 2 weeks it go to the point that i had to go to the hospital and then be told nothing was wrong .. pain is like af cramps but 2x stronger ! I can’t sleep i don’t wanna lay down or sit then the lower back pain starts they gave me really strong pain killers that honestly just knock me out .. i don’t get it :( I’m really starting to stress over it
