Thoughts in the order I'd check (some or all may not apply):

0. Make extra-sure your module's enabled on admin/build/modules

1. Check your drupal_add_css() call. Should look roughly like:
drupal_add_css(drupal_get_path('module', 'MYMODULE') .'/css/MYMODULE.css');

2. Make sure you're doing drupal_add_css() inside hook_init()

3. Test with css aggregation (admin/settings/performance) turned OFF on production and verify that your css appears in the head tag. If it doesn't, sanity check: make sure you're updating production code correctly (a simple comment in page.tpl.php or your main stylesheet works), check the watchdog for obvious errors.

4. Turn aggregation back on, see if css shows up now

5. If not, clear cache (admin/settings/performance)

6. Verify that you don't need to restart memcache/apache/etc, do it if needed

7. Go back to step 0 and try again

Good luck.
