Hi i am Dr Ahmed Aly thanks for using HealthareMagic site , I had gone through your question and understand your concerns .. Actually amitriptylene HCl is a type of antidepressant used for balancing chemicals in your brain . sometimes used as a painkiller or a sedating agent to help you sleep with patients having severe chronic pain . You could not use it without your doctor prescription especially with Prozac as both antidepressants may cause severe side effects sometimes very dangerous or even fatal with increased doses . In my opinion if you have a kind of neuropathic pain pregabalins or gabapentin will be more reliable but you have to ask your trating doctor for best dosing if you are using any other medications for other health issues . You may avoid heavy lifting , over weighing , vigorous movements , bad sleeping or sitting postures and high cholesterol or high protein and salty components and you will feel better soon . For my patients i recommend painkillers like advil tab when needed , hot gentle massaging with topical gels of anti-inflammatory , B12 vitamin supplements , muscle relaxants will be effective for most of cases . steroid tabs or injection may be needed in more sever cases . B12 supplements and pregabalin have best results with nerve pains , if pain persist i recommend some lab investigations like urine analysis , ASOT , Rheumatoid factor and X rays , MRI and follow them up with your physician for proper evaluation and management of the underlying causes of such nerve pain .
