Hi! Thank you for reaching out. My main symptoms were the muscle tremors, overall chest pain, radiating nerve pain, overall fatigue, and difficulty with sleeping. For the pain management and sleep disruption, my PCP started me on a low dose (10mg) of Amitriptyline and a regimen of Low Dose Naltrexone (LDN) with the hopes of resetting my central and autonomic nervous systems - I've been increasing dosage from 1mg to 4mg presently (increasing 1mg every 3 months) and my pain is much improved, I am sleeping well again, and I've had nervous system functioning (heart rate, tremors, muscle spasms, GI issues) almost restored to normal. LDN is higher doses is given to opioid overdose patients with the hopes of resetting their CNS and helping the body to naturally produce endorphins. I hope you find this helpful and please reach out with any questions, Steve
