I've had a repeat performance every single night for the past several years. Only with mine, it is a bad back - one that doesn't stop any daily activities whatsoever, but becomes a vortex of the most unimaginable pain every evening.
He spends the entire evening after the kids are in bed, rolling around on the floor (his favourite place to watch tv from), and groaning... occasionally yelping when I don't seem to be noticing his agony enough. Oh, and refuses to do anything that might actually help - like painkillers, or a heat pack.
I just can't do sympathy any more. I resent it. It interrupts every single thing I'm either trying to study, or watch. The evening is my only chance for peace and quiet and he's flopping around like a fucking beached sea lion not getting enough attention (referring to the noises and flippering only, not anything less flattering).
I might have more sympathy if I hadn't suffered my entire life with a broken back that never healed properly, and chronic pain as a result. I take painkillers, use a heat pack, go to bed/bath if I really can't bear it, the end!
