Hi there...I can understand your concern. Which joints do you have pain in? And what nerves swelling do you have? It must be varicose veins you are referring to. Joints pain at your age can be due to rheumatoid arthritis, osteoarthritis, osteoporosis, obesity, psoriasis arthritis. It will need detailed clinical examination and further tests to diagnose. Kindly consult a orthopedic for further evaluation. You will be taught strengthening excercises, started on calcium tablets. If needed even steroids. You should start reducing weight. Avoid climbing stairs.
