Hello Dear
I evaluated your concern in depth .
@ This much weakness after recovery from
pneumonia is not normal at all
@ Possibilities are as follows :
1. Initial diagnosis was not confirm only as pneumonia , it may be having
associated underlying pathology not detected / missed by clinician .
2. Pneumonia is still not controlled & pathological process inside the body is
still going on
3. Emergence of new condition during or after recovery from Pneumonia
@ Moral of the story is that you require thorough history , physical
examination , further detailed work up to reach at the root of the issue
and get final management guidelines .
Hope this will help you definitely .
Feel free to ask any further health related query in future anytime .
Thanks for using Health care magic .
Regards .
