First of all, we should pay attention to rest, strengthen the warmth, avoid cold, you can hot compress ironing, to wear loose shoes, avoid wearing high heels. Usually avoid strenuous exercise, especially playing soccer and basketball, track and field sports. Generally you can apply topical Fitalin cream and Flurbiprofen Babu Cream, you can also carry out localized closed treatment, use Lidocaine Hydrochloride injection as well as Trimethoprim injection for 2 to 3 times, most of them can get good relief. In the case of corns you can apply corns cream, conservative treatment is not effective and surgical removal is required.
