<bot>: Hello dear, The symptoms as mentioned in your post can be attributed to:1. Compression of nerve fibers at the knee region due to maintaining inappropriate sitting posture.2. Inadequate HY Chat Doctor.  Dietary deficiencies of certain nutrients like Iron, Calcium, vitamin D, Vitamin B12, Folic acid, etc. which help in blood formation & nerve conduction.4. Peripheral neuropathy caused due to any fluctuation in blood pressure or blood sugar level. Symptomatic relief can be obtained by intake of cervicogenic agents (like Vitamin B6, Vitamin B12, Folic acid) as well as multivitamin & multimineral supplements including iron, calcium & vitamin D needs to be added in your diet. Physiotherapy & postural exercise will also be helpful. If symptoms still persist, kindly consult a Neurologist & get a complete Neurological examination done. Certain investigations like complete blood count, serum electrolyte estimation, fresh estimation of blood pressure & blood sugar levels & nerve conduction studies will be helpful to rule out any pathological cause for the symptoms. Wishing you a Good Health. Take care.
