GO! Pain will be forgotten, as soon as dopamine/serotonin dump happens. If you are Not in any type of 'medical harms way', I say Go. If a crash could/would/could do permanent damage, then Do NOT go.... But if its just pain/sore... you will block that out as soon as you start concentrating. Thank me later
I've had two of them in my low back L4/5 before my surgeries, all I can say is fuck that shit. Mie hurt like hell and didn't help at all
