<s>[INST] I broke my ankle several years ago and have no problems until the last two weeks when I became sore after a 10mile walk some of it on uneven ground It now aches when I walk or stand too long. The doctor thinks it is most likely arthritis and we are waiting for x Ray results. I am planning a 10 mike cycle ride tomorrow, a lot if it down hill and i will take it easy but would it be better not to go at all, could I do some serious damage? David Reed [/INST] Hello and Welcome to ‘Ask A Doctor’ service. I have reviewed your query and here is my advice. Your ankle is bad and as arthritis has set in will restrict ankle movements and make them painful. If you overuse your ankle then you will have worsening of symptoms and pain. I will suggest moderate exercise are best. Hope I have answered your query. Let me know if I can assist you further. </s>
