Muscle spasms in the chest symptoms and conditions

I have been on Omeprazole for then past 18 months. It did control the acid reflux however I've suffered with dizziness and joint pain for months. More recently I got muscle spasms in the chest and what felt like heart palpitations. I was ready to schedule a battery of tests but decided to stop taking the Omeprazole first. Within 24 hours of stopping use the symptoms stopped. after 72 hours I felt better then I had in months.
