Going out and about whilst signed off sick?

Hi all,

I had an operation a couple of weeks ago, in total I've been signed off from work for 5 weeks. I've got two weeks left off of work. I'm at the point now where I feel ready to be able to leave the house etc, but I know I am not ready for work yet.

I am just worried about being seen out, like say i go and try do some food shopping, or go for a little walk. Obviously I'm not skiving off, but if someone from work sees me, could I get in trouble? I am sooo fed up of being stuck inside whilst its lovely and sunny out.
