Airplane headache and heating issues

so yesterday i got back home from a holiday and as the plane was descending i got this really intense headache. ive had bad headaches but never this bad. it continued on for a couple of hours but now its gone, something that is still here tho is my trouble hearing through my left ear. theres this slight wooshing sound and i can hardly hear through it. its been 17 hours since i landed. could this be problematic?
