I often have very warm, wet sensations on/in my right outside thigh. This started just about a month ago, but some days I have as many as perhaps 10 occurrences a day. There is no pain at all associated with this. I had my right knee replaced a few months ago and wondered if there was any connection. I have never heard of this happening to anyone and it seems so bizarre. I will be 72 years old next month and have never been diagnosed with diabetes. My kidney function is perfect and my spine was Xrayed last week to see if a nerve was being pinched.
