I ve been experiencing left arm tingling, lightheadedness, chest burning, and weakness off and on for over a month. I went to the hospital on May 25th and after extensive testing, CT Scan, MRI, blood work, ultrasound of the heart, and arteries in my neck, they said I had a TIA and all the tests came back fine. I will have 1 good day, and then the next day it all happens again. I am over this and don t understand why it keeps happening??My LDL was alittle high 107, so they put me on cholesterol medicine. I have been dealing with this for over a month, and can t get back to my normal life routine with me feeling like this. Please do you have any answers????
