Hi,
BASED on the information it seem your are having issues with "ADRENAL GLAND" which in turn secrete EPINEPHRINE which is know to cause Flight or fright reaction, which is know as "Adrenal Hyperplasia" that can cause uneven release of that hormone can cause the abnormal increase in heart rate , that need s to be addressed by ULTRA SOUND and biopsy.
About the dizziness, may be due to some low blood sugar/ low pressure and their many cause for it,
***(A) LOW BLOOD PRESSURE - CAN put you to dizziness/loosing balance if the blood do not reach sufficiently to brain's center for balance due to some compression / obstruction in the blood vessel)
causes for low blood pressure
a) Hypothyrodism (low thyroid hormone, associated with fatigue, low energy and weight gain)
b) bradycardia (low heart rate)
c)
heart failure (heart to weak to pump blood)
d) liver diseases
e) low sugar
f)
Postural hypotension (position induced low blood pressure)
***(B) LABYRINTH APPARATUS PROBLEMS ( a organ present in ear which helps the sense of position)
cause of problems
a) Menier's Diseases , ( person feels dizzy, and associated with some
hearing loss)
b)
Viral labyrinthitis (person feels dizzy, or sensation of room moving around , vertigo)
c) Otolith (small stone in ear canal makes feed dizzy , but dizziness comes at certain position/movement only).
d) Problems with the
vestibular nerve (hearing/balance nerve)
ADVICE:
1) If possible try to CONSULT PHYSICIAN /
NEUROLOGIST (Brain doctor)
2) There are number of test that still needed to be done in order to come to conclusion which are as follow
a) May need CT-BRAIN with dye to check the blood supply channel.
b) blood test of thyroid hormone level check, lever enzyme profile, sugar level
c) physical test for
orthostatic hypotension (position induced low blood pressure)
d) Audiometery to check any HEARING changes/problems
e) labyrinthine stimulus test to check the apparatus.
hope it helps
