Wanted to post an update. I have been taking Betahistine (SERC) when the dizziness gets bad and has been working quite effectively. That in conjunction with IMT (Intramuscular Therapy - trigger point injections) has helped immensely. My neck is about 60% better and dizziness is less of an issue. I am now able to go to the grocery store, malls, etc. I do still have symptoms come on, but about 20% of what they were previously and I haven't had to take a nausea/anti vertigo med in over 3 weeks now. I went to Walmart last night, which is a big accomplishment for me, as Walmaert would always make me sick...I was walking around, shopping and honestly hardly even noticed any symptoms for the first time in a year! Considering symptoms were still moderate to severe 3-4 weeks ago, I'd say that this therapy has really helped me. I had previously been doing physio 2 times per week for 9 months, with little result. My neck would always seize up again a day later and symptoms of dizziness/nausea would come on strong. From what I've researched I knew that getting the neck under control could only help the post concussion dizziness that I've had for almost a year now.

I'd encourage anyone with concussion + moderate to severe whiplash to consider IMT. There's a clinic in my city that does this technique, however don't see as much online regarding it. They inject what's similar to a dental freezing agent (lidocaine) deep in to my muscle tissue, at points that they define as triggers. This immediately released tense muscles at about 10 trigger points in my neck. The doc says like night and day when examining my muscle stiffness afterwards. As soon as they inject, my muscles completely relax. This allows my body a more long term solution of muscle relaxation and time for more oxygen to be delivered to the muscle tissue for healing. It hurts at first, but has helped big time with stiffness, soreness and the rest of the whiplash symptoms that I've had since Aug/13.

Now all that I need is more time for my brain to heal more. I know that I'm not out of the woods, but this therapy really has helped me out of the several treatments/therapies/tests I've done over the last year. PCS symptoms have been reduced in half (if not more). I would be interested to see if the treatment could help someone else as much as it has me.
