Hello, Numbness in the joints of the hand can be due to arthritis or carpal tunnel syn Chat Doctor.  Numbness in the knee followed with lightheadedness is commonly due to developing arthritis, spinal disc issues, peripheral neuropathy, etc. You are suggested to get clinically examined by a neurologist, get nerve function & Imaging tests done.  Get CBC, Urinalysis & blood tests done to detect the pathology causing the discomfort. In the meantime take food rich in vitamin B1, B6, B12 or supplements. Do regular exercises, walking. Avoid addictions if any. Your treatment will depend on the pathology detected & your clinical condition. Hope I have answered your query. Let me know if I can assist you further. Take care
