Welcome to Neuro Talk. Sorry about your fall. I love riding too. I am 60 with other issues but I understand the PCS and some of the symptoms you have.
Others will be by to guide you also. You can and will get better. Many folks on this site improve, so have hope.
If anxiety is getting to be a bit much, go back to your neurologist, and write down all your questions OK? Write down all your current symptoms.
I believe the weight gain is from the stopping of smoking. this happens to most people who quit. good for you, just keep walking if you can and the weight will come off. It is worth the added pounds to get the habit out of your life! Don't stress about it, just get well and eat as healthy as you can.
I do know that PCS and any kind of bleed in the brain, takes time to recover from. I am glad the bleeding stopped in the hospital.
Try not to think about what happened to your mother. Remember just because our parents had something bad happen, that does not automatically doom you. You don't necessarly get what your parents had. Genetics is only one small part. You were healthy and riding when this accident occured. You can be healthy again.
Welcome again to Neuro Talk. You will find alot of friends and information here. ginnie
