I am now 37 years old, but began experiencing similar pains when I was about 23. I had all kinds of stress tests, blood tests, scans, and monitors. I was diagnosed with "anxiety." I would have symptoms during the day, while sleeping, and they progressively became worse over time. The only medication that helped me was Lorazipan and Busbar. (Spelling is probably incorrect.) The Lorazipan was addictive, so I was taken off that and was put on Busbar, which wasn't near as effective as the Lorazipan. I became pregnant and was a "witts end," when I decided it was time for me to find an alternative. I chose natural medicine, homeopathic remedies, and it absolutely worked! It took a couple of weeks for me to really feel the effects of the remedy I was taking, but it was the best $300 I have ever spent in my life! I would so recommend that you take this route and atleast try it. You'll never be the same. I still have a bit of anxiety once every 3 to 6 months, but it's not daily - most of the day. Most importantly - pray. God hears prayers and answers in His timing! Blessings.
