Sorry to hear of your daughter's struggles and pain. She sounds like a trooper as she deals with the pain.

Has her doctor tried amitriptyline in small doses (10 mgs)? It helps some with PCS. Is her blood pressure in a normal range? It can cause the headaches if it gets too high.

If she is going to try some school work, be aware of any frustration she may have. Stress (frustration) is bad for recovery. Also, if she gets concerned about falling behind, that anxiety is not good.

Help her find some relaxing activities to do. Things that involve using her hands tend to be slow and non-stress. Knitting, sewing, crocheting, painting, or any simple hand crafts can be good. The hands cannot work too fast for the brain. Handicrafts is a common therapy at brain injury rehabilitation clinics.

Regarding pain relievers for the head aches, her problem is very common. I use a mix of Tylenol and aspirin for my worst head aches. I too, live with headaches to the point that I have learned to ignore them.

Sounds like she is handling things pretty good. All you can do is help her keep the stress levels down.

My best to you.
