Mastoid inflammation: when you have mastoid fluid this can be acute or chronic. If it is chronic - it is often from prior mastoid infection. If it is acute you will have focal pain and possible fever. It can actually be a very serious condition. In general this should be dealt with by a physician who might determine if you need antibiotics. The other findings are not related. Optic neuritis is blurred vision.
