My Daughter Has A Frozen Shoulder And The Doctor Want

My daughter has a frozen shoulder and the doctor want to prescribe one of these medication. Neorontin, Amitriptilyne, Norco. I was reading that neorontin is for seizures, Is the doctor prescribing the right medication? The other solution the doctor said is an operation that is not recomendable. I never though a frozen shoulder is so complicated as years ago I couldn't comb my hair but it was resolved with physiotherapy. Thank you
