Chemical. I had the first part on Thursday morning, now the second part today.
I’ve had two of the chemical tests, and what they showed was that there was nothing wrong with my heart...it is very strong. But my lungs were causing the angina I kept having, so I was given a nebulizer and three different medications.
Since then, (maybe 18 months) I haven’t had even a twinge of angina. If I feel the numbness in my left arm or the pain between my shoulder blades, I have a breathing treatment and the pain is gone almost before I am done.
:o]
I hope your test reveals nothing to worry about!
