Hi Warriorservant
What you have been describing sounds very familiar to me. I am a long time lurker here but decided to join recently.
Please take a look at this thread from my home from home. its not by me as i was led to believe that vast areas of the astral have been cleared now so people can project without harm or fear.

Anyway, i hope the thread is of some use to you. It is entitled Astral combat by a poster that seems to be displaying a lot of the symptoms of injury etc as you.
i projected the first time about a year ago and took a nose dive into my bedroom carpet, not knowing how to stop lol. My body started holding it's breath as if i was going under water so i was brought back.
Then i was startled/semi attacked on another projection by a nasty entity and haven't tried again since.
Past/future ( yes future ) life regression sounds like it might be beneficial. i don't know where you are based but i can recommend the college of psychic studies in London from first hand experience. ( won't post link, need to read the rules lol ). They have several practitioners there that i think might be able to help in many areas.
I'll leave it there for now, good luck.
