Hey there,
I've been having breathlessness associated with muscular pain and spasms in my back and stomach for a few months now. I do have asthma and have ruled out heart problems (EKG and echo) along with normal blood tests and a lung function test. Nonetheless, I keep getting momentary "anxiety attacks" but don't really feel stressed. I've been to the ER twice from what I thought were heart attacks (numbness, tingling, cant breath, head pressure, etc.) and I'm not sure what else could be going on.
I've noticed a bit of an indent beneath my right rib cage and when I exhale i notice that this area seems to be thick with pressure. Could this be a rib that is out of place? Or is this more likely lung-related. My asthma has been under control for most of my life after 10 yrs old due to singulair and advair. So I'm not prone to get asthma attacks. I was also doing a lot of weight lifting in the preceding months before the symptoms started.
