Antidepressants often have the side effect of causing muscular pain and insomnia and digestive problems -- very common side effects. Part of the reason is that these drugs use the same pathway into the brain as magnesium, so if you take magnesium at the same time as the drug the drug won't absorb well and the drug inhibits the absorption of magnesium, which is responsible for relaxing us and our muscles and nervous system. Sometimes you can solve this problem by taking a good magnesium taureate or citrate supplement to compensate, but it has to be taken at a different time than the antidepressant or benzo. Other than that, Luvox isn't used much in the US, so most Americans have little experience with it.
I can understand and completely relate to your anxiety regarding heart issues. I've had several of my own that sent my anxiety levels off the charts.
While we can help you with your anxiety, I think you would best be served right now by going to our Heart Health Forum and talk with Jerry_NJ. He is the community leader of that forum and is very knowledgeable about the type of heart issues and tests you're dealing with. He is also very understanding about anxiety.
Please understand that I'm not blowing you off, but most of us on this forum are just not as "heart savvy" as Jerry.
You are ALWAYS welcome to come back here for more help with your anxiety.
You can just copy and paste your post into the Heart Health Forum.
I hope I can offer just a little reassurance first. You are under the care of a cardiologist and you must trust that he/she would order any further testing if they deemed it necessary. I also understand all the "research" you did, but without adequate medical training, looking up cardiac symptoms can and WILL, as you said yourself, be extremely traumatizing.
Also............talking to a friend, even if he IS a doctor, can be VERY counter productive. He does not have all your test results and the only advice he should have given you was to speak with your cardiologist again. Any more than that is a bit unethical.
I hope you will post in the Heart forum. I think you will get the answers you're looking for there.
I wish you the best and that your anxiety is quickly resolved.
