sorry sir dj.. dami ko na warning's sau.. di m mauulet  
pwede po ba matanong kung ano ang hanapbuhay nyo, kasi kung mga 1 a week ka lang naman naglalaba ng mga kumot na niyuyuko mo hindi yun enough to cause those kinds of pain, kahit nga mga labandera hindi nagrereklamo eh yung araw araw nila ginagawa, i think pag kumot time since you exert a lot of effort para buhatin at banlawan nagexacerbate yung back problems mo from a possible injury na nakuha mo sa ibang paraan
unless your like john cena who lifts as much as edge+bigshow on his back, the washing wasnt the cause(unless mga 50 kumot yung nilalaban mo)
better go to a CNS specialist to get it checked up better, as advised Ortho is a good place to go to
since its only when you wash its still ACUTE, dont allow it to become chronic na kahit wala kang ginagawa sumasakit unless you want to end up getting extremely painful streroid shots to your spine
now sa chest pain may i ask do you smoke and hows you BP?
um sa avatar mo i see you use a smoking pic so
sa paglalaba mo use proper body mechanics, back straight when going down to pic up bend your knees and lift with your legs not your back
