I'm sorry to hear about your Mum's symptoms, this must be so distressing and upsetting.
Please do give us a call on 0808 800 0303 and speak to our advisers and nurses about this, and what you can do next, they will also be able to help you with support.
We also have an information sheet which might be helpful too, with tips on what to do, what can cause this and where to find more support and information.
I hope this helps, please do let us know how you get on.
