I have been having some health issues that the doctors have not been able to figure out. But because I'm a nurse, I have done some research and have my theories. Back in Feb I started having a lump in my throat. The lump has not gone away. In fact, it is getting bigger. I really didn't think anything of it because the doctors thought it was due to stress, and school, yadda, yadda. In the past 6 weeks I have been noticing symptoms of increased heart rate sometimes up to 140 beats/minute. Been in th ED 2 times, and having episodes of these palpitations, dizziness, and shortness of breath. It hit me while sitting in the ED. Could his be my thyroid? Doctors said its not the thyroid because hormones are normal. So here I am stupified about this situation. I got curious a couple weeks ago and did a google search and found that I could have problems with my thyroid and still have normal levels--something that the doctors don't have a clue about (I guess thats not their specialty). While researching, I found that the symptoms (SOB, increased HR, dizziness, fullness in the neck, ears hurting, but nothing felt on the outside, normal hormone levels) could be indicative of a thyroid cyst, nodule, or cancer. I went in yesterday for a CT scan but I won't know the results until Monday. This is killing me!! Not knowing what to expect is so difficult. My question to you is: Do you know anyone who has had anything like this? If you do, please email me privately at firstname.lastname@example.org . I would appreciate any input, or inspiration regarding this. Thanks for reading if you have gotten this far!
