For the most part the pain med I take has allowed me to be pretty comfortable as well but there are those days that hmmmm, maybe I sat too long, bent over too many times, lifted something that I shouldn't have or whatever and *the dreaded pain* ensues... yep~ sure know what you're talking about tho am very glad for U that your P-discs are holding up well and so R U!
Hope your painfulness will be gone tomorrow or very shortly thereafter
