Sorry about this problem you're having Julie. I never had a supra pubic drain so I don't know what to tell you.
For general surgical area pain:
Maybe an anti-inflammatory like Ibuprofen instead of aspirin. Also try heat and try ice alternately. Decide which one seems to work better for you and just use that.
Check with you internist though.
Hope this gets better for you soon!
