bmx hurts

yeah, I threw out my lower back/hip area again. everything was going fine, I was hopping dark patches of new pavement on a deserted side street, then I went for a sideways grass gap and the pain began. my low tire pressure is working great! especially the front wheel as I need to smoosh it before I do a manual/wheelie/turn kind of thing. and for dropping curbs to the right. they both start with a sideways smoosh and turn type of movement. I got some cannabis leaves from joe today and they smell like elephant dook. also my 4 day weekend that surrounds my birthday is coming up in 2 days. no idea what to do for 4 days with no order picker access to correct back problems. wish me luck.
