Hello, Thanks for writing to us, I have read your query, This can be due to pinched nerve in spine. Due to compression of nerve root there can be swelling in your foot. I will advise you to do MRI spine and EMG-NCV [Nerve conduction study] and consult to orthopaedic surgeon. Peripheral numbness/swelling is common in diabetic . Change your diet and remove inflammatory foods such as citrus fruits, dairy products and wheat that may aggravate peripheral neuropathy. Simultaneously increase your intake of potassium and calcium-rich foods such as bananas and avocados and green leafy vegetable. Vitamin B12 is important in the maintenance of health and normal functioning of the nerve tissue and deficiency of it can lead to numbness. You can increase B12 level by taking meat and fish, or you can take Inj methylcobalamine. Hope this answers your query. If you have additional questions or follow up queries then please do not hesitate in writing to us. I will be happy to answer your queries. Wishing you good health. Take care
