More concerning symptoms would be those suggesting a significant infection, a blood clot, low oxygen, or heart/lung distress. The photograph alone cannot rule these conditions in or out.
A cough lasting more than 3 weeks, unexplained weight loss, drenching night sweats, persistent fever, recurrent chest infections, or breathlessness that is slowly worsening also warrants prompt clinician review, even if it is not an emergency.
The symptom combination of sudden breathlessness, pleuritic chest pain, cough, leg swelling/pain, or hemoptysis is recognized in pulmonary embolism assessment (Fuster and Hurst's
The Heart, p. 526). Emergency warning signs for shortness of breath are also summarized by the
NHS.
