<s>[INST] I am 50 years old had Ct scan and us found cyst in left kidney tingling and numbness in both legs down to toes weak tired cant even fold a load of clothes let alone walk without assistance. Please help getting no help from doctors. One says orthopedic another says endocrinoligst another says nephroligist [/INST] Hi, Thanks for asking. Based on your query, my opinion is as follows.1. Cyst size in left kidney is important for management. If small, it can be safely ignored.2. Tingling and numbness is possibly due to diabetic neuropathy or It B12 deficiency.3. Meet a neurologist to identify possible cause. If you have any back pain, Ct scan may be necessary. Continue treatment with It B12 and biopic acid. It could show improvement within two weeks. Hope it helps. Any further queries, happy to help again. </s>
