I Have Been On Pain Meds Due To A Surgery

I have been on Pain meds due to a surgery that went bad.I am now on disability because the doctor refused to come back to the hosptial.I had to be life lined because the doctor refused to answer.A simple galbladder surgery.I had to be bagged all the to a Trauma Hosp.and in a coma.He did nothing!! I am 58 and lost my husband in 2011 from a heart attack in my arms at home.Is there a treatment to get me off pain meds with out sever withdrawls.I lost all my long term memory.And now have many problems.There is not a day goes by that I am not in Pain
