My husband is a Type I Diabetic, well-controlled, 66 years old.  He has been walking two miles a day, and recently experienced edema (pitting) to one ankle.  He injured the ankle a few days later and went to an instacare, where he was told he had injured (pulled) several of the tendons in his foot.  He is now experiencing shooting, burning pain that has kept him from sleeping for the past two nights.  I have some voltaren gel from a previous injury.  Would if be of any benefit to him?  He has tried elevating his foot and applying ice packs.
Hi do check his uric acid levels. Also apply ice, followed by ointment, and tie with Pleistocene bandage--twice a day. If the pain is too bad at night, give him Ibuprofen/Diclofenac with Omeprazole at bedtime. And do show your doctor--regards
