Problem with this is I'm now using the back of my hand or other parts of my body to open doors, press elevator buttons etc...

Partition your body: some parts used for some things, others for other things. Use an elbow or knee to push buttons, use the long sleeve of a jacket as a mini-glove if you need to grasp a handle. Or wear gloves that you take off once you're inside.
