Hey. I've been having a hot water bottle consistently for around 2 years. I have to have one, I have had major stomach problems for ages now and it takes the ache away but I think it's become more of a comfort and I can't be without it, even in the midst of summer. Thing is, it's left brown marks all over my stomach. It looks awful 😢 has anyone else experienced this and if so, is there anything I can do to get rid of them? I know not using the bottle is the obvious one but anything else? Thanks x
