Do I have a case against a long term healthcare facility that let my father get a bed sore that became so infected that he had to have his leg amputat

You may have a viable case. Look for an attorney who specializes in nursing home negligence cases. These are decidedly different causes of action than medical malpractice cases because they are grounded in regulatory law. If you want to investigate a case, you should contact a local medical malpractice attorney (one in your state).  They take these cases on a contingency basis which means you only have to pay if you succeed.  Click here, for more information about me.   Please understand that by answering your question in this informal forum I am not acting as your attorney. I am not doing anything to protect any legal rights that you have.  Medical malpractice cases need to be thoroughly investigated and to know whether you have a viable case, an attorney usually has to obtain and review all of the pertinent medical records and consult an expert.  John Ratkowitz, Esq. 105 Eisenhower Parkway Roseland, NJ 07068 Office: (973) 830-8441 Cell: (732) 616-6278 Fax: (973) 226-0031 Email: jratkowitz@starrgern.com.  Click here for my website.
