have a bath, it will help you feel better. Just don't have it too hot, and only use gentle soap etc.
take whatever you have for the bone/muscle ache, and then talk to your team about preventing the same degree of 'discomfort' (haha, medi-speak) next time.
we don't have a bath at home, but I wanted one so badly (on the same chemo as you) that last saturday night I booked a flash hotel in town, bought some lush bath products, and luxuriated in the 5-star luxury! (Got one of those cheap deals from lastminute.com, only cost 100 bucks.) It was worth every cent.
go for it!
