Hi, personally on bad pain days I feel exhausted! I think where I'm trying to just get through the day my body is fighting the pains so by the time I get home I can fall asleep on sofa. When my hips,legs are bad I feel I've run a marathon and got no energy left!
If I'm having a better day I still get tired but not to that extreme. I try to have one good layin at the weekend and it's not unusual for me to get up midday, but I find this helps give me a boost to cope with the next week. Last weekend I was up early as family visiting so am now feeling shattered! The only thing that helps me isa good sleep! I'm not sleeping properly at the mo I think it's partly pain waking me and knowing there's only 2 weeks to my big op I'm starting to get a bit nervous so that's not helping either!
I was also told taking painkillers constantly can make you tired too but I'd rather be tired than in pain so my only way to cope is to sleep !!
Hope that helps and you find a way to help feel better too x
