Hi, If I were your treating Doctor for this case of
tingling and heart palpitations, I would come up with three possibilities, these include:
The first possibility is of heart rhythm disorders. Diagnosis can be confirmed by EEG. Try to avoid alcohol or drinks with caffeine in them, or eat chocolate or spicy or greasy foods. Follow Potassium,omega 3 enriched diet-banana,raisin,carrots,potato.
The second possibility is of
Hyperthyroidism. TTH, T3,T4 should be measured to rule out it.
The last possibility is of
Dehydration. For this purpose you need to keep yourself hydrated with plenty water during heat wave.
I suggest you to consult a physician and get examined.
Hope this answers your question. If you have additional questions or follow up questions then please do not hesitate in writing to us. I will be happy to answer your questions.
Wishing you good health.
