If i do anything remotely active, even standing up and walking into the next room, I can't catch my breath. It feels like I can't breath in fully. I have asthma, but it doesn't feel like asthma. I've been sitting still most of today. Peak flow is a little below normal, but not really concerning (390 - I'm usually 450)
I'm also exhausted, aching muscles from walking upstairs.
I was recently found to have low iron levels, but not sure how low, and I'm waiting for results of a second blood test.
I'm third day into a fairly heavy period, tmi, but it may be relevant if this is an iron level thing.
The breathing is bothering/worrying me, as it is worse today, and I will be ringing the dr tomorrow, but was hoping for some reassurance or opinions as to whether this is an iron level thing or something else, and is there anything I can do immediately to improve my breathing?
