As you have said that you are diagnosed with Lupus. Lupus is a collection of autoimmune disorders
. In layman, your own body is destroying your organs and in your case it is mostly lung and joint.
That is why you are put on high doses of prednisolone
to suppress your overactive immune system. once you recovered from asthma
, you will be on plaquenil
which will prevent destruction of joints from inflammation. You know your line of management and do what your treating doctor suggests you.
Wish for good health.
