Hi and welcome
It took me almost two years, 3 trips to ER, before they finally diagnosed me with Fibro. My PCP was the one who dx me. The last time I went to ER I thought I was having a heart attack. The drs in ER were useless and sent me home, telling me to see my PCP the next day. It was not my heart, but was costocondritis. I went the next day to my PCP and alls he had to do was touch a few tender points and I flew off the table. I never really thought about Fibro, until I couldnt stand the pain anymore in my legs, back, thighs, chest, and neck. I am pretty sure mine started after major surgery in Jan of 2005. Hope you start to feel better soon. Some days it is normal to feel useless, but that is ok. Be kind to your body and it will thank you for that.
