Thanks for writing to us.
Eventhough I am unable to examine you as a limitation of internet, I can clear your doubts by analysing your symptoms and suggest few remedial steps.
The differential diagnosis could be 1) deficiency anaemia for which you can undergo complete hemogram/stools microscopy/urinalysis
and if you are a female gynaec consultation as well.
; if you are middle aged and having obesity/sedentary life style/family history of BP and Diabetes
kindly consult a physician and investigate for the same.
3)Hypo/Hyper thyroidism; May present like a condition mentioned above. Most likely Hyperthyroidism
4)Panic Attacks/ Hyperventillation Syndrome;- Usually in young girls of reproductive age group.
Kindly consult an Internal Medicine specialist locally available to come to an evidence based diagnosis.
All the very best,
Dr Lt Cdr ASN Bhushan.
