Dear Sir/Madam,
For the last 6 weeks I have been suffering with the following system:

1) Dull aching pain in the center chest area (Constant).
2) An occasional burning sensation in the center chest and sternum.
3) An occasional (slight) nausea feeling.
4) A slight feeling of being short of breath.

I have recently had a full examination with a Cardiologist, who was able to rule out any heart condition.
The issue started after one night of consuming large amounts of cocaine. It was a one off, and I do not take this drug (or any other) on a regular basis.

I am a 47 year old male Caucasian. I'm 5'11 and weigh 203 lbs. I'm in good physical condition and frequent the gym (4 days a week). I'm a non-smoker and drink very little alcohol. My eating habit is healthy. My only vice would be my coffee intake (4-5) cups per day.
I was advised by the Cardiologist to take a NSAID (Aspirin) for two weeks following the cocaine consumption along with PPI (Nexium). Since then, I have stopped taking the Aspirin but still take Nexium 20mg twice daily.
Questions:
1) How long should I be taking the PPI for? ( I’m concerned with having to take this medication on a long term basis, due to any side effects)

2) What could be the cause for this to be persistent/constant?

3) Are there any specific test’s that I can have done?

Any help would be much appreciated.

Kind regards,
Steve
