Hello Tyler,
It is good to know that you want to meet a doctor.
You can meet a Physician who will order a few tests to know your physical status.
He might order an ECG, treadmill test, repeat
thyroid profile and complete blood counts.
You might be having low
hemoglobin which has probably resulted in this severe
shortness of breath. However, your cardiac condition also needs to be evaluated. Do get your thyroid status evaluated again as any amount of low dosage if taken, can also lead to breathlessness. Do try to meet a Doctor of internal medicine at the earliest and get yourself tested.
You require to take a good nutritious meal along with mild to moderate exercise. Try to relieve your body aches with topical pain killers, if necessary you can taken
NSAID painkillers in future as required.
If you have any further queries, I will be happy to help you.
