Many thanks for your helpful reply. When I have the spasm
s in the diaphragm area my abdomen does not become hard. I get a pain
like a stitch in my left hand side, my sternum becomes very pain
ful and sore, like the skin has been burnt, so sore
I cannot bear to touch it.
s affect the secondary muscles of respiration, which is the cause of the breathlessness. Are not the secondary muscles of respiration smooth muscle?
