<s>[INST] My friend has developed a severe blink that has now has turned into a facial parralasis when he try s to talk, he has had a very traumatic time over the last few years and I thought it may be psychological but I fear it may be something worse. The blink can last 5 to 10 seconds before he talks. [/INST] Hi, Thank you for posting your query. I have noted your friends symptoms. Based on the description, he seems to be suffering from bifacial spasm. If you can upload a short video f his face at rest and while he speaks can help confirm the diagnosis. Botox injection treatment can help in bifacial spasm. I hope my answer helps. Please get back if you have any follow-up queries or if you require any additional information. Wishing you good health, Chat Doctor. Ly/ </s>
