I got this bug while doing the MQ when the Greybeards told me to go retrieve this artifacts in some cave/dungeons while I'm dare I fight 3 spider in the very end around the parts where fire is being blown from the ground if any of you guys remember that part in the dungeon and then after I kill the spiders I am permanently stuck in walking as if I have past the limit in items even though I don't and I can use alt to run, instead shift turns into a infinite sprint which is a really annoying bug because I don't walk to infinite sprint or be stuck on this extremely slow walking style if i don't use shift to infinite sprint, does anyone know how I can fix this? I have tried fast traveling into another zone, and sleeping and if I use my other saves I would loose 5 complete hours of questing

please help
