Suggest Treatment For Dizziness, Fatigue And Labored Breathing
Check the thyroid hormones ;
I have gone carefully through your concern.
Your symptoms are suggestive for many pathologies.
The change from armour thyroid to levothyroxine needs a close follow up. 6 weeks after changing the tablets you need to check the TSH level.
Meanwhile check the blood pressure.
Of course, some other biochemical exams are needed to exclude diabetes, anemia ect.
So I would suggest a detailed clinical examination and some blood tests .
Other causes to be excluded;
So untreated thyroid and anemia are not the causes if your symptoms.
Causing dizziness and dyspnea are too many conditions but the most common to exclude are: cardiac arrythmia, middle ear infection, anxiety disorders, pulmonary problems etc.
So a detailed clinical examination would be helpful in finding the pathology.
