Hello.. from the brief description the pain appears to be of a non-cardiac origin. The following caveats will apply :- sweating, breathing difficulty, vomiting
, pain associated with walking.
As you are a sportsperson, consider a muscular origin of the pain/discomfort. usually as a unnoticed trauma in the form of a "jerk"/' straining' or a push.
The point in favor of this is that it increases on deep inspiration.
Suggest you use a Diclofenac
50 mgm every 8 hrs with Omeprazole
20 mgm at bedtime anad locally apply a heat fomentation / ice as you feel comfortable with.
These kind of injuries do take about 15 days to heal.
On the RSVP issue, please check the BP. this measurement has to be taken seriously only if you have a lung condition as chronic cough
/ smoking / hypertension
Wishing u good health
