The conversation between human and AI assistant.
[|Human|] I am struggling with the sensation of "floating" and dislocation.  I have been awaken from my sleep feeling dislocated and lightheaded.  I had a stroke in December 2012.  After reading and working on my computer I begin to feel dislocated and sometimes double (shadow) vision.  I have a lot of weakness on my left side.
[|AI|]  Welcome to Chat Doctor, I had gone through the case and found that it might be due to formation of clot in carotid artery which effect the circulation of blood to brain and causing these symptoms. So Immediate go for Carotid Doppler test to find the exact size and location of clot. Take proper Conspiring dose after diagnosis to dissolve it. Hope my answer will be effective for you. Thanks, Chat Doctor.
