Pain control medication advice needed?

So went for a massage 17days ago, lady did mention I was VERY tense, I told her to continue being firm. I got the expected aches and pains for couple days, after 3/4 days tho it became excruciating in neck shoulder n top back on left hand side, 6days index finger went numb, 9days masseuse advised contracted muscle putting pressure on nerve. 11days ring docs they say I already doing everything (cold compress 24hrs then hot naproxen, rested for wk in sling and now slowly exercising) 16 days and the pain is still making it impossible to sleep (understand how sleep deprivation is torture) and can't take no more. Ring docs again and given me amitriptyline... am I able to take this with my bipolar and split personality? I take 75mg quatiapine and 80-120mg propranolol. Was told when first diagnosed bi that anti depressants previously made me worst. Apologies for rambling and thanks for reading. Should I take newly prescribed amitriptyline?
