Hi welcome to Health care magic forum. The spot you have mentioned is not a major problem, cause could be anaemia, fungal infection
, but never concerned with pneumonia
or present u.r.t.i,
you can neglect it , but if you are particular about it you can consult a dermatologist
, for diagnosis and treatment.
You should consult a physician for the present, upper respiratory infection
, as it may leed to pneumonia like lower respiratory tract
Wishing for a quick recovery and thanks for calling.
