Pain
"I took 10mg, 3x day hydrocodone for a year prior to a new pain doc in a new state requiring I switch to Hysingla ER. I had only had one 10mg hydrocodone for each of the two days prior to beginning the Hysingla so this was not withdrawals. An hour after the 20mg pill, my heart was pounding hard, short of breath, which progressed to severe abdominal pain, nausea, the worst pain of my life (easily 2-3x my very worst days with stage 3 adhesive arachnoiditis, Ehlers-Danlos, and innumerable tarlov cysts on my spinal cord), joint pain, muscle pain and spasms, and I could literally feel my CSF pulsing in my spinal cord. The doc actually made me take a second dose because she thought I was in withdrawal. I vomited the 2nd one and nearly aspirated it"
