I got it, a Spa...get a massage. Some cities frown upon them and then some are a rip off or are like for women mostly.
But Spa's are a legitimate business--many of them, checkout your yellow pages and make some calls if they are listed for your area
You get some company and companionship....last spa I was at had rap music blasting and really cool chicks but those aren't allowed in the US as far I know
But still, really, Spas are nice, they got all types and some have hot tubs and your back should feel better. Even if you got to travel a bit...a spa a week might keep the doctor at bay
