Yes, you should have a walking stick at least. Canes are difficult IMO.

The walking stick alerts others, and they will avoid you. Huffing and puffing some helps too.

I am better in warmer weather, and terrible in cold weather. Seems the cold freezes my large muscles in the thighs and back.

While I don't have much pain from PN compared to my arthritis, but it is all very depressing. So I keep busy with things, and that helps.
I work here on the boards, I am clearing out my studio and getting ready for some major art work, I play with the cats, do some Ebay shopping for supplies and material for still lives... and just keep busy. I pace myself, move around the house, play a few Angry Birds, do the meals, etc. But hubby shops mostly now for food and other things. He is retiring next month, so he won't be griping so much I hope. There are still a very few shows I watch on TV, but I do go to bed early and rise early. That is my new normal. I've had to avoid most of the CNN news, and other downer type shows. Violence makes me ill and depressed, so there are not many TV shows I can enjoy anymore!

When Feb rolls around I'll be starting my seeds for next summer, and that keeps me positive and occupied. I really don't socialize much anymore. My best friend is very busy at her job over the holidays, and we get together in January and springtime. Neither my hubby or I have any family left alive, except for our son, and he is mega busy with his job, etc. sooooo.... we are hermits of a sort. I rather enjoy the peace, compared to my nightmare noisy stressful job which I have escaped from!

It is difficult getting older, and trimming the life down to what you can handle. I totally sympathize. Keep positive, and do the best you can... baby yourself when necessary, and keep on truckin'.
