If she has a neck injury, lying in bed can be a problem. It is easy to have bad head and neck posture in bed. From what you say about her impacts, I would not be surprised that her primary issues is her neck and not her head.

The subtle neck injuries require consistent discipline with head and neck posture. One study showed that 80% of concussion had a neck injury component with the neck injury often being the cause of the majority of the symptoms.

A headache clinic may dismiss the neck injury issue. A pain clinic might be better.

Where in Calif is she ? I can research doctors for her to seek out. Is she on Medi-Cal or another health plan ?

Is she able to work at all ?

Has she applied for Social Security Disability ?

Was her concussion 3 years ago documented by a doctor ? Those records would be valuable so her current condition is considered in context with her concussion history. From what I understand, the ER is not a good place to go for migraine pain meds. An Urgent Care Clinic would be better. A regular doctors clinic would be the best.

She needs to establish a history with a clinic so they regulate her access to pain meds. This way, she does not show up looking like she is shopping for narcotics. She may benefit from a muscle relaxant like Soma (carisoprodol). It is not as strong as oxy but may help if she has muscle spasms in her neck.

It would be good if you put together a binder with her medical records. I doubt she has the focus to do that accurately. Her Washington medical records can be requested. They will want a "Release of Medical Records" form filled out first.

It is great that she has an advocate like you. This can be a tough road to go alone.

My best to you both.
