What Do The Following MRI And X-ray Scan Reports Indicate?

Question: My mother, age 82, decided to stop walking due to fear of falling, and she is in a wheelchair. She has had x-rays (no fractures), MRI ( some bulging discs in L-3 and 4, plus slight stenosis, resulting in sciatic pain) and leg ultrasound (some plaque buildup). However, she can stand up and move her legs around. She has always been very sedentary. The doctor put her on Tramadol, 50 mg 4x per day. Yesterday she put her on Gabapentin and Baclofen for pain after physical therapy ( which was so severe the two times she went that she doesn't want to go back) My dad gave her all three last night and she slept way longer than normal, over 12 hours with one bathroom visit during the night. This morning she is extremely agitated and annoyed. The doctor said to take the Baclofen after PT, but the bottle states 3x per day, so my dad did that. Her other meds include for hypertension, cholesterol and mild diabetes. Her weight is about 130.

Do you have a recommendation regarding the timing of taking the medications? I see there is an interaction between the Tramadol and Baclofen with regard to sleepiness. She slept 13 hours, from 6:30 to 7:30.
