See a doctor: Are you able to consult a physician to get a full evaluation? Are you mobile and able to get to a clinic or hospital? Do you have someone who can take you? Can you schedule a consultation with a HealthTap doc who can assess the urgency of needing an in-person examination? It is not possible to diagnose what you have without more information. Best wishes.

Possible lung: The symptoms you give are suggestive of something going on in your lung or your right upper abdomen. What ever is happening should be checked out by a physician as soon as possible. Without a further work up, it is difficult to know exactly what is happening. See your physician.
