I Have Been Prescribed Hydrocodone Approx. 7-8 Years. 7.5 I

I have been prescribed hydrocodone approx. 7-8 years. 7.5 I have scoliosis with stenosis, in my lower back. My legs hurt so bad, and also I had 4 knee replacements on my left leg. Yes 4 of them. some were only 6 months in between, and no time to heal before them. I stopped my hydrocodone yesterday. Cold turkey. I only took what was prescribed...1 or2 tablets in a 24 hour period. My question is...what can happen to me for completely stopping, cold turkey. is it safe to do that? You are too expensive for m. I am disabled from all the knee surgeries. And scoliosis with stenosis. But thank you anyway.
