sent me for a pulmonary/hypertension test. It showed I have an overload of fluid that is causing pressure on my heart, which is why I'm so short of breath. The problem is that I'm getting very weak and my appointment at my local hospital is still 4 weeks away. I had a bad weekend and feel really awful today. I am having trouble walking my breathing is bad, I feel generally unwell and I am having trouble staying awake. I won't be able to get a gp appointment for weeks. I am tempted to ring for an ambulance but I don't like to make a fuss. What do you think I should do?
