Pablo,
Try a topical prescription NSAID inflammatory. Have your doctor write your a prescription for 10% ketoprofen w/ 5% tetracaine as a PLO.

PLO stands for pluronic lecithen organagel and can be made by a compounding pharmacy-ask if they can make a PLO. The ketoprofen is like ibuprofen, an NSAID, but has local effects and the tetracaine is an anesthetic to numb the area a little. PLO tpicals penetrate the skin and work where they are needed while minimizing systemic absorption and side effects.
You have to pay out of pocket for a PLO since 99.8% of drug insurance only cover non-compounded manufactured meds but the potential for pain relief is worth the price.
