Welcome to NT
This is a great place to come and find support and answers.
My mom was on Cumadin. It's a tough drug to take. After 10 years or so, they ended up putting a filter in mom, for clotting factors. She is not on blood thinners after that. Every person is different in their needs and why they are on blood thinners. You should wear a band for your own safety.
So sorry you're having so many problems. It's not easy, I'm sure.
Did you get copies of your medical records? I'm sure there's a lot of tests, labs, scans, etc, that will give you lots of answers.
The more informed we are about our medical history, the better our chances of successful treatment in the future.
Caregivers and healthcare providers do want the best for their patients. I do believe that, in spite of some medical provider issues I have of my own. But on the whole, I do believe we need more attention when it is not clear why things are not right with a person.
Be wise. Be informed.
It may help to keep a diary for future reference.
Give yourself time to heal. Concussions are hard to get over sometimes.
Be very careful of hazards around you that may cause you to lose your balance. Falls are your enemy. Take every precaution till you're steady on your feet. Be safe above all.
Get plenty of rest. Keep hydrated and listen to your body.
