Patent Claims:	1. A method for treating a patient with combination therapy, said combination therapy comprising: administering a therapeutically effective amount of an oral NSAID; and applying a topical diclofenac preparation to a knee of said patient to treat osteoarthritis of the knee of said patient, wherein said topical diclofenac preparation comprises a therapeutically effective amount of a diclofenac salt and 40-50% w/w dimethyl sulfoxide, wherein the therapeutically effective amount of oral NSAID is the amount required to achieve a therapeutic effect in the absence of applying a topical diclofenac preparation. 2. The method according to claim 1, wherein the patient is treated for severe knee pain. 3. The method according to claim 1, wherein the patient is treated for breakthrough knee pain. 4. The method according to claim 1, further comprising: conducting periodic laboratory evaluations regarding said patient and the combination therapy. 5. The method according to claim 1, wherein said diclofenac preparation comprises about 45.5% w/w dimethyl sulfoxide. 6. The method according to claim 1, wherein said diclofenac preparation further comprises ethanol, propylene glycol, glycerine, and water. 7. The method according to claim 1, wherein said therapeutically effective amount of diclofenac comprises a pharmaceutically acceptable salt of diclofenac selected from a sodium salt, a potassium salt, a diethylamine salt, or an epolamine salt. 8. The method according to claim 1, wherein said therapeutically effective amount of diclofenac is 1.5% w/w diclofenac sodium. 9. The method according to claim 1, wherein said oral NSAID is a member selected from the group consisting of a COX-2 selective NSAID, diclofenac, tenoxicam, meloxicam, celecoxib, diflunisal, etodolac, fenoprofen, flurbiprofen, ibuprofen, indomethacin, ketoprofen, ketorolac, mefenamic acid, nabumetone, naproxen, oxaprozin, piroxicam, sulindac, and tolmetin. 10. A method for applying topical agents to a knee of a patient with pain, said method comprising: applying a first medication consisting of a topical diclofenac preparation to an area of the knee of said patient to treat osteoarthritis of the knee of said patient, wherein the topical diclofenac preparation comprises a therapeutically effective amount of a diclofenac salt and 40-50% w/w dimethyl sulfoxide; waiting for the treated area to dry; subsequently applying a sunscreen, or an insect repellant to said treated area after said treated area is dry, wherein said step of applying a first medication does not enhance the systemic absorption of the subsequently applied sunscreen, or insect repellant; and wherein said subsequent application occurs during a course of treatment of said patient with said topical diclofenac preparation. 11. The method according to claim 10, wherein said diclofenac preparation comprises about 45.5% w/w dimethyl sulfoxide. 12. The method according to claim 10, wherein said therapeutically effective amount of diclofenac is 1.5% w/w diclofenac sodium. 13. The method according to claim 10, wherein said diclofenac preparation further comprises ethanol, propylene glycol, glycerine, and water. 14. The method according to claim 10, wherein said therapeutically effective amount of diclofenac comprises a pharmaceutically acceptable salt of diclofenac selected from a sodium salt, a potassium salt, a diethylamine salt, or an epolamine salt. 15. The method according to claim 10, wherein said step of subsequently applying comprises subsequently applying said sunscreen. 16. The method according to claim 15, wherein said sunscreen comprises oxybenzone. 17. The method according to claim 10, wherein said step of subsequently applying comprises subsequently applying said insect repellant. 18. The method according to claim 17, wherein said insect repellant comprises N,N-diethyl-m-toluamide (DEET). 19. The method according to claim 17, wherein said insect repellant comprises 2,4 D dimethylamine salt (2,4 D). 20. The method according to claim 14, wherein said therapeutically effective amount of diclofenac comprises diclofenac sodium.
