Regular exercise is essential but for the immediate situation, these work for me:

When aching shoulders were keeping me awake, Magnesium malate provided immediate relief.

When 8 hours of Bulgarian dancing had my knees complaining, a heavy dose of MSM/glucosamine sulfate (4000) enabled me to dance another 3 hours pain free and continued doses had me upright and pain free to host the Tribute to Woody the next day, dancing through most of it.

The later has also helped twinges in the hip which started a couple days ago. But I ignore the recommended dose and take as much as I need. After the dance workshop, I hit as high as 7 at one time and then went down to none after a few days. (I use a pendulum to determine dose. Works for me!)
