Tingling burning pain in hand when using iPhone

If that were true then you don’t need to post on a user forum about it. You need to 1. Take the phone to Apple for inspection and 2. Go see a doctor. It is unlikely you are feeling energy from the phone but those tingling zaps and heat…are more likely some sort of nerve damage you have which can tingle and feel like zaps with heat. To find out for sure go see your doctor. But posting on here will get you nowhere. You aren’t talking to Apple and we are fellow users that can not diagnose you.

The phone does not radiate any sort of energy other than heat. Most likely what you are feeling is caused by RSI or Carpal Tunnel Syndrome, but you should consult a doctor for a diagnosis.

Go see a doctor, no it won't cause cancer.

No one on this forum are doctors or can diagnose whatever you are feeling. You should go see your doctor.
