You can try doing what I do. If I have a pain somewhere, I give it 3 days before I start getting concerned. We all have little aches and pains, that is how our bodies deal with all the stress and garbage we put in it!
About the urine, when it is dark, it defineately means that you are dehydrated, especially if it has a distinct odor. So drink some water or have a lot of fruit. Your urine actually can tell you a lot, specifically if you have a poor diet, then it shows up in the urine. Like stated earlier, give it a few days. Drink lots of water, eat water rich foods, like fruits and raw veggies and salads, then keep checking your urine. It should clear up after a while.
Hope that helps!
