Hi...
Please trust your doctor when they examine and tell you all is good . There is no glaucoma.
If due to some reason, you are not comfortable, not satisfied with any explanation...take a second opinion.
But do not try to read and diagnose disease.it is not that simple...pressure of 21 does not mean glaucoma,moreover it is NCT, and in your prescription it is showing 18.5 also.
You can look for other causes of headache ...like migraine, stress headache, sinus issues.
Use a lubricating drops.
All the best .
