Sleeping naked

So I love sleeping naked, it feels amazing and there’s health benefits from it. Bonus! However I have been cold in my room lately so I haven’t slept naked . I did for the first time yesterday tho and I woke up with a terrible shoulder pain. Do u think they are linked? Maybe the cold air struck my back while I was sleeping??? Is it possible? Thanks.

Btw I have fibromyalgia and sometimes suffer from shoulder/ neck pain
