"Tip pf the day." Droll, very droll.
I had one that helped my lower back pain, but when this whateveritis pain ramped up in my left hip/leg it made that worse.
I bought a $150 table from a guy for $50. He said it didn't work. I pointed out to him that it wasn't assembled properly, but he was so pissed at it he sold it to me anyway.
I gave it to a guy whose wife had a kidney stone. He said the doc told her to hang upside down an inversion table. I had never heard of that.
