Thank You.. Last Week I Came Out Of Hospital After

Thank You.. Last week I came out of hospital after 4 days due to kidney problem it went to 20% in a month from 50% in August.. I was dropping things and falling. anyway I have been told I have Asthma last night I got this pressure on my chest and back, I had the peramedics out as I have no idea weather I would get worse in my sleep. anyway all is well not even muy heart. but I am still worried when I sit still I am ok but as soon as i walk from my room to room in a flat I am exhausted and sweating .. should I keep wanting answers
