How long have you been working at WM now? If it's not very long (a week? two weeks?)-- over time, your body will adjust to the physical activity. I'd say also that it's important that you get enough calories. While your muscles are trying to recover from the big jump in physical activity, is not a good time to be trying to restrict yourself to say, 1200 calories. I don't know what your range is or how many calories you're eating on average. Or what other exercise you're doing. And getting your water is important.
I'm assuming your doctor cleared you for this work, so there's no underlying medical issues that could be causing joint pain. So it would just be the increase in activity. Many people swear by soaking in a bath with epsom salts. I know when I'm working my body harder, some extra sleep can help. Also Arnica gel is a homeopathic remedy that can help with muscle aches and stiffness (I bought some at WM). Sometimes using ice can help; sometimes using heat feels better.
