Hi i am a 35 year old female. For over a year now i have been suffering left arm pain along with tingling and numbness, jaw pain, back pain, chest pain, shortness of breath( feels like i cant get a deep breath and yawn alot to get a good breath), headaches and fatigue. I get off and on swelling of my feet and hands towards my monthly cycle time. I have been having hot flashes off and on for a couple days now also. I have been to 4 cardio's to check my heart cause i though these were all signs of heart disease, every test is normal so is my thyroid they say. I am to the point where i cant take this anymore, i am on ativan for my anxiety over all these symptoms. I just want to find out what is wrong with me. Does anyone here have any advice??? Please!!!
