For the past 4 days I've beem experiencing pressurw and shortness of breath. I'm trying to rule out dust because MI'm staying with my son who just moved into an older home and he's constantly working on it. He also put an air purifier in my bedroom,and I started taking a probiotic and an anti-allergy pill. Still no relief. I was taken to the hospital via ambulance this time last year and they found two blockages and an aneurysm – 4.2. I'm just not sure if i should take myself in for a check up.
