<s>[INST] I had Bi-lateral knee replacements 6 years ago. Since then I been having pain at the bottom of the left toe when I walk. This happens from time to time. If I squeeze my toe I feel no pain, but when I walk it is very painful. Do you have a answer. Thanks Vinnie [/INST] hi vinnieThe toe pain may be uuunrelated to knee surgery.Have an x ray done and check up by a orthopedic doctor.it could be isolated interphalangeal joint or phalangealbone problem.Do hot fomentation and apply  voltaren gel  twice dailythanks </s>
