Hello. I am 29. 5'5". 150 pounds. Lost 100 pounds in 9 months without surgery by cutting all fats, carbs, etc. Now within the past month, I woke up 3 times in middle of the night with extreme chest pain coming right from the middle of my chest. Pain lasts about 20-30 minutes. Pain is worse than child birth. Then, I regurgitate a couple times and I feel better. I would like to also mention that I do have gas with this too, sometimes I feel I can't burp and I really have to. 3rd time around, my husband called 911. Rushed to the hospital, I felt like I was dying. They did blood work, Cat scan, X-rays. They said one of the tests came back where I might have stones, either in my galbladder or kidney. I feel extremely tired, my chest is ofetn tight and it feels like there is something stuck in between my breast bones. They want me to go for an U/S for both my gall and kidneys and they want me to go for an upper endoscopy. Kind of afraid of the tube going down my throat. Oh yeah and I also drank that barium drink and they said they didn't see anything wrong with my esophogus. Anyone know what it could be? I also have a really bad headache right now and I NEVER get them. I have always been so healthy. I feel like I was healthier before I lost all this weight. I feel like I am falling apart. Headache, chest pain, knot in my chest, and I feel VERY tired right now and I feel like I am in a daze, almost like I had a few drinks. Any advice would help. Thanks.
