Dear sir, these symptoms definitely means something and you should visit hospital. You didnt mention for how long has it been like this but fever
are signs of acute respiratory infection which can be mild or severe. This left sided pain can be caused by lung inflammation, bit also gastric disordes such as GERD
and ulcer should be considered. These waves u re describing are significant for angina pectoris
so cardiology workup shoud be done. So the conclusion is that you have at least 3 organs which need to be checked up. I advice you to visit your GP as soon as possible and plan your next steps.
Wish you good health, Dr. Ivan Romic (Rominho)
