I am 28/F/5'9"/163 lbs.
I have been having symptoms of hyperthyroidism: heart palpitations in my abdomen/neck/legs, fatigue in leg muscles after normal activity, minor muscle cramps in abdomen, overall fatigue after normal activity, frequent bowel movements, anxiety. I went to the doctor on Monday and had a blood test, and the thyroid levels came back normal at 1.8. He also checked my BP and listened to my heart and he said everything is normal (pulse is also normal). However, I am still having palpitations throughout my body and have muscle fatigue in my legs after normal activity. What can be causing these symptoms? The palpitations are not flutters but rather strong pulsations that coincide with my heartbeat and feel almost like a vibration – it sometimes feels like its moving parts of my body and it has even woke me up at night. And the muscle fatigue – I just walked up the stairs from the train station (routine every weekday), and my leg muscles felt tired and had a slight burning like I had been exercising too long. I have also felt slightly warmer and harder to tolerate heat in the last few days even though my temp is normal. These symptoms started last Thursday (8/5) and have not gone away, although some days/nights are better than others. I had an upper GI scope in March which discovered a small hiatal hernia. I do get reflux and occasional heartburn, but nothing severe. I eat healthy and drink lots of water. I don't smoke and drink only occasionally. Any suggestions?? :confused:
