"i have a herniated and degenerated disc, sacrum joint disfunction and piriformis syndrome. it was very disabling, unable to get about, get dressed the pain was 10/10 had to crawl while being pregnant. if i did a lot of activities pain was on its way. popped pain relief did physio, went to gym, good diet, tens machine. nothing really worked apart from being in bed for 3 days till pain eased. i have 3 kids and really thought my life was going to be living in chronic pain. i was prescribed amitriptyline for headaches. any-way i asked my dr for these meds for my back, so she agreed. well i have a new lease of life! i still get stiff and have to re-crunch (set) my back but haven&#039;t been a day in bed since starting them this year i take 20mg."
