Hello,
You have not mentioned your age, but in elderly females close to perimenopause, hormonal changes in the body can cause such symptoms. The other possibilities are anemia, thyroid conditions and anxiety and panic attacks. Get your hormone levels, hemoglobin levels and thyroid function tests done to rule out these conditions.
It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided. For exact diagnosis, you are requested to consult your doctor. I sincerely hope that helps. Take care and please do keep me posted on how you are doing.
Sometimes it really helps to change doctors, and get a "fresh pair of eyes" on the problem. You know your own body better than anyone, and if you feel something's not right, it's probably the case. Do you have any support from family, friends?
I've been to the doctor many times. He has run blood tests and done check ups and says everything is fine and can't find anything. He thinks it's just my anextiety. I don't think it is. I am a 32 yr old male.
Have you been checked out by a doctor?? How old are you?
