The discussions here seem to be very conflicting, the reason I made this topic was because I was diagnosed with a damaged Autonomic Nervous System which is unrelated to opiates but because of this neurological condition, I experience adverse reactions and hypersensitivities to my opiate based pain medication.
During these reactions I get all sorts of intense weird symptoms sometimes effecting my vitals and other times odd sensations like a build up of pressure in my skull and sinuses, wriggling and tickling sensations in my brain, muscle spasms, feeling confused, agitated, sedated etc so I'm wondering how much of that is doing physical damage or killing brain cells.
After the opiate wears off I feel fine but I'm still curious as to any physical repercussions opiates may have on the body in general, as I have to be extra cautious in maintaining my health due to the medical condition I already have.
