I am 27 years old. the NP in my drs office told me a couple of years ago that I had a heart murmur. nothing was done about it. My dr. never noticed even tho I wore a holter monitor one night until the np said something about it. He gave me adipex last thurs. the past couple of days ive been really tired, kind of lightheaded, and a little bit of pain in my chest. when i just walk say to the kitchen at a normal pace my legs hurt kind of like ive been walking on them all day nonstop...I guess they just feel tired. I have been walking a mile a day since last friday..I didnt walk today tho cause I have felt so bad. Could it be from the adipex?
