Thanks for all your advice.

I consulted already a doctor, but still the same meds he prescribed however the pain is still continue or should i say it's getting more. There are times my stomach are also affected and i fell pain already at my back. This past few weeks i fell a severe pain, and that I suffer a difficult in breathing.

I worked inside a very noisy area (i.e. Chiller room/Pump room)

Please help me.
