If it's muscle sorness, then a massage to warm, strech and relax the muscles does wonders. Especially if one is so lucky to have a partner willing to give it to you. Love heals!
Otherwise there are a zillion herbal oils and ointments that help. Look for stuff made of essential oils of eucalypt, chammomil, lemongrass, juniper, marjory, lavender, rosemary... They all warm the muscles.
But if the pain was caused by smashing into the mat one time too many (and especially if there is bruising) look for stuff to cool the sore spots rather than warm them.
If, however, the issue is bone-related, then by all means go see a doctor. I have great experience with a chiropractor - he certainly did more for me than all the docs put together - but you decide for yourself.
