Leg blisters and sudden weight loss

Hi

I have gone from 10stone 5 pounds to 8 stone 12 pounds in the past two months, with no changes in eating.

I also had a blister on one inner thigh which I hadn't noticed until it had burst and it was sore due to open skin wound. I now have 2 very sore hard blisters on my other leg. They are on the inner thigh about 2 thirds away from the knee.

They are not large, but are very painful

Could this be related.
