Thanks for the reply, Mark.

I was prescribed Ativan for sleep issues directly after sustaining the concussion in August by a primary care doctor. I took 12 1 mg pills at bedtime over a three week period, and then quit cold turkey after talking with an ER doctor. Sadly I ended up back in the ER three days later with what I later realized were withdrawal symptoms.

Unfortunately i am still taking a dose of .8 mg/day as I've struggled to taper off the drug. Still taking the drug has contributed significantly to my continued sleep issues. I held off tapering during October/early November to get some rest and and let my brain heal, which I was successfully able to do to a large extent. This setback is discouraging, as I now have headaches again that had subsided back in late November.

I am now actively tapering the Ativan again and have been getting back to work on a part-time basis. With these headaches and the stress that comes with my work, I may need to pull back from work again for a bit and focus again on healing and tapering.

Thanks for the thoughts on neck injury. I saw a vestibular therapist earlier today and she referred me to a PT who specializes in neck/spine issues.

Regarding the head shaking event earlier in my recovery, this was an involuntary response to a combination of drug withdrawal and insomnia. I was not sleeping much at all, and also trying to taper the Ativan. Soon after I started taking Gabapentin to help with sleep and have spread out my doses of Ativan to reduce interdose withdrawal symptoms. I have not had the head shaking experiences again since spreading out the doses and getting better sleep.

Back to the jumping and resumption of symptoms issue, is jumping and landing something that could commonly rekindle some of my PCS symptoms?
