Question?: what are you asking: mastoiditis is a serious condition, usually a bacterial infection which defintely requires antibiotics and sometimes surgery. Recovery depends on the extent of the infection and surgery.

Infection: Mastoiditis, usually an infectious complication of middle ear infection from the same side. It can be acute or chronic often requires imaging studies, along with other tests. Medical management is often tried first before surgical intervention is considered. While some allergy symptoms may mimic s/s of mastoiditis, experienced physician should be able to diagnose it without difficulty.

Head ache: "Mastoiditis" is over read on MRI by radiologist. If CT is ok with no bone erosion or complete Opacification then easily treated with meds. It may be unrelated to your HA. If you have no nasal or sinus congestion or middle ear fluid then you don't have clinically significant mastoiditis. you've been on abc and antihistamine already. You will at least get a good head $ neck exam from ENT.
