Hello, There are many reasons for chest pain, but with FM it seems to be a broader pain than just pain over or around the heart, and muka57 is absolutely right about the trigger points, check it out and have someone help you test the different trigger points, be sure to mark them down, 11 of the 18 different spots is a very good indicator of FB, it seems like people with FM almost have to diagnose them selfs. It was helpful for me to keep a pain diary, and to list what you were doing, what brought on the pain ie: working resting and such, decribe the pain with words such as dull, sharp, burning, stabbing and so on. include what made it worse and what gave you relief. Do this for about a month so your Dr can see exactly what is going on. I have had Fibro for 20 years and have found that most GP's don't seem to be all that versed on FM. If you can, finding a good pain managment Dr is to me the most important thing. You need one who is willing to LISTEN and not rattle of the standard mumbo-jumbo, You are the expert in this situation because it is your body. And most definately it is cyclitic, in my own case I refer to my days as good days and bad days. I have constant pain all over, but it also can be in one quadrant of the body and not another, but generaly I have more pain in my upper back across my sholders, it is a burning pain and at times it is almost impossible for me to do the simplest of things. What I have found that helps me is a hot shower, and some days I will sit in the shower 3 or 4 times. At the present time I am on 3 medications for the FM, a pain pill, Neurontin and Cymbalta, this has helped a lot, but am now at the point I feel I need a muscle relaxor too, I have gone through 3 pain managment Dr's and the last one and I clicked, he took a lot of time listening to me and giving me options, so I didn't start out on all 3 meds at once. He also told me I needed to be kinder to myself, I always tried to push through the pain and felt guilty and embarrased if I didn't, but you know since I have started being my own best friend lol, I feel better, if I am having one of my bad days I just sit and do something relaxing, looking in the garden books and planning my flowerbeds and garden is one of my favorite things, and if I don't feel like getting out of my PJ's I don't.... You did not say if you worked or not so staying in your PJ's may not be an option dress code and all lol. I also use a lot of humor to help. It is very infuriating to be in pain and not be able to get relief, I read anything and everything about Fibro so as to try to be as knowledable as possible,and I can be very pushy when I think something will work for me, but my Dr is willing to give it a try, So I can relate to what you are saying being a kindred soul and all lol, I don't intend to sound like an expert on anyones pain/illness [because I am not> but knowledge is power. I am always sorry to hear of someone suffering through any chronic illness and I wish you the best in finding relief, hope this has helped in some small way. Good Luck and please let us know how it is going for you.
