This condition is rare. I have encountered only a handful of people with this over the years.

Some people, rather than pain, can also experience orgasm at the moment when they start to exit the physical body.

I do not know precisely what causes this oversensitivity to energy and OBE.

The cure for this is to focus on meditation, energy work, and Lucid Dreaming...including Wake Induced Lucid Dreaming.

Then I suggest you come back to OBE once or twice a year and make an OBE exit attempt. At some point these frustrating symptoms will ease and you will be off.
