Dr said I had fluid in my ear. I took sudafed for two days, is that enough? Or what do I need to do? I cant even tell I have fluid

Get rechecked. It is hard to tell if you have no symptoms but if you did have fluid in your ears, Sudafed for 2 days would not likely do the job. People with fluid in the ears usually notice a sensation of ear fullness (plugging) and/or hearing loss.
