Hi there ~
I understand your concerns. I think the pain in back, chest, underarms, and discomfort are all due to back problems in your spine. However you also have lupus, emphysema
that complicate the picture. However, I would advise you to consult a neuropsychiatrist who is well versed
with treating multiple pain disorder. I wonder if you could consult one to find the right medications for you.
I hope this helps. Take care and have a lovely day!
