I've been having concussion like symptoms for about 6 months now. I just started Physical Therapy 2 weeks ago and it has been helping very much.. I recommend it to anyone who hasn't been feeling any better after 5 months or so. I also upped my dose of Nortriptyline from 20 MG to 30 MG, I have noticed a significant difference in how I feel. It has definitely helped me start feeling almost completely normal. I just wanted to share some positive news. I know how depressing and hopeless one can feel after so many months of not feeling better. This is more of a recovery post. It is possible, and can happen to you to. Just keep a positive outlook and keep praying and working hard toward recovery. I have also noticed I feel the best after a good workout. Every time I leave the gym now its almost like I feel as if I have zero symptoms at all. Thank you for reading!
