Damodar,

Welcome to NeuroTalk. You may have PCS but from what you describe, there is not enough information to help you much.

If it was something more serious, your doctor would have picked up on those serious symptoms and prescribed some tests.

If you tell us more about yourself and each of your injuries and the symptoms right after those injuries and any other health issues, we may be able to be more help.

My best to you.
