Would this be sinus infection or sinusitis or is that the same thing?

For about 7 days now I have had (sorry to be graphic) but I have had extremely thick yellowish brown mucous coming out of my nose but I have to blow soooo hard to even get anything to come out, I dont feel sick i dont have a cold and never had one this just started with like a burning sinus and dry throat type feeling and now today everytime I blow my nose its bloody. But I thought I would be sick with a sinus infection, I feel perfect. besides feeling all this mucous stuck back there somewhere.

You need to see a doctor. When it is green it is an infection but dont wait that long.

A guy I know died of a sinus infection because he waited too long to see a doctor. The infection traveled to his brain.

sinus infection = sinusitis

itis means infection

From your description, it could be a sinus problem but not necessarily sinusitis. Try an over the counter decongestant and see if that thins out the mucous so you are able to move it out of the system.
It's not good to blow your nose that hard because it forces mucous with germs in it into your sinuses and it sounds like you're breaking some blood vessels.

It's better to irrigate your nasal passages with salt water or a neti pot to get the little cilia in your nose working to push the mucous out.

Certainly sounds like a sinus infection. See your doctor. If you let it go untreated, it will get worse and can even spread to other areas.

PLEASE see a doctor the infection can eat the lining of the skull reach the brain and it's over.
