I need help w/pain management from Ulnar Nerve Decompression surgery?

Surgery performed 3 weeks ago on right elbow. Am on Short Term Disability. Am allergic to almost all pain meds & anti-inflmmatory meds. I have some which were prescribed by Doc, but I've been nauseated the past 48 hours from taking too much. The pain is almost unbearable & appears to be getting worse. I called Doc's office today to request we pursue more aggressive recovery treatments. However, besides icing it once I get off computer, what else will help? All I can ingest now is ginger ale to calm my stomach. I haven't eaten in 2 days.
