Before you seek and spend money on alternative treatments, it will be worthwhile to consider what symptoms you want to are treat.

There are no broad spectrum treatments for PCS. Individual symptoms are usually addressed individually.

I had iicp from a concussion for about six months - it makes me think of the bleed you suffered from.

I had some acupuncture for several months and it helped me a lot with the pain. I think it worked a lot better than the narcotics I was prescribed, but my Dr. and acupuncturist both said that it works differently for everyone.

I see a chiropractor once a month. I was seeing him weekly for months though, I had to until my muscles were able to hold all my joints etc into place better like they used to (6 months of iicp made all my muscles atrophy).

I am currently experimenting with homeopathy. I read an article that researched its effects treating people with PCS and the conclusion was that it would be worthwhile to do more research about it. It was conducted by a reputable Western Medicine source. I intend to post a link to the article in the sticky at the top of the forum one of these days... I've noticed some good things since I started, but I'm doing so many things, I can't say which are really helping and what's helping more than time for me - it's been 20 months or so since the accident I was in that gave me the mTBI... so it could just be time and the fact that my physical health is improving.

I also recommend tai chi, yoga and meditation. I consider those all to be "alternative" practices as well, but I find them very beneficial. I meditated and practiced yoga before the accident.

I also take BCAA's as a supplement. I found some research articles that indicated they might help people heal faster from a mTBI. I put that article in one of the threads stickied to the top of the forum.

My acupuncturist also recommended that I take CDP Choline,
Phosphatidylserine and D-Ribose and my neurologist approved all of them too.

After 4 months, the symptoms that I'm dealing with are headaches, generally daily for the majority of the day. I've had headaches of differing severity since day one of the concussion. They tried Tylenol w/ codeine in the hospital, then elevated to dilaudid and ibuprofen. After twelve days inpatient, they sent me home with a script for those and told me to follow with my GP. After a follow up at 3 1/2 weeks with the neurologist that treated me inpatient, I was referred to a concussion specialist neurologist. He stopped those drugs and told me to take just Tylenol and prescribed Depakote as a prophylactic for the headaches. I did two runs of prednisone of increasing dosages. Neuro was concerned about "rebound" headaches fron so much pain killers. They helped somewhat at the start, but didn't last. He then prescribed Tramadol and amiltrityline. He then told me he thought the rebound headaches were the true cause. I haven't taken any pain killers of any kind for over a month. I have headaches everyday. Generally severity increases the more I try to do. Sometimes they get worse for seemingly no reason.
I also have focus / concentration problems, short term memory problems, am easily distracted and can't seem to complete tasks. I get easily irritated and my emotions are not always as controlled as I would like. I have sensitivity to bright light and get easily overwhelmed by too much information or crowds.
