Hi @Helenv,
Welcome to the forum. 
I hope that our wonderful members will be able to provide some feedback, and I’ve also found two previous discussion you might fight interesting about breathing and coughing problems and shortness of breath.
We also have a free and confidential helpline with a team of amazing advisers who could provide additional support and advice. Please feel free to give them a call on 0808 800 0303 or email at [email protected].
Best wishes,
Nikos
