Conversation: The conversation between human and AI assistant.
[|Human|] I thnk I have a recurrence of CFS (my body is drained after minor exertion), but am a little worried by a loss of power in my hands. I can t do delicate things, nor can I do things that need strength, such as opening a jar. This has been going on for a fortnight.
[|AI|]  Hi, Sudden loss of strength occurs because of derangement of nerve supply to the muscles. It may occur at any level from brain to very junction of the muscles with the nerves. Sometimes, myopathy (pathology of muscles) itself may present as sudden weakness, but muscle coordination remains intact in case of myopathy. You need to get muscle charting done along with blood investigations focusing on markers of inflammation and myopathy. Only after this, we can reach a diagnosis. Hope I have answered your question. Let me know if I can assist you further.
