I'm 19 years old and i've been having pressure in my left eye for a few days? am i at risk of having glaucoma?

Needs evaluation.: There are a number of causes, in and around the eye. Rather than going through the list , you should be seen. Hope there is no blurring of vision. Sinusitis, migraine variant headaches, are amongst causes for the same. A good optometry exam can easily rule out glaucoma. Since it has been a few days, i would recommend a check up.
