Clogged feeling in my ears and occasional popping. lightheaded also. no apparent sinus issues. any ideas?

Yes, some ideas: The ear symptoms are often related to congestion of the nose and throat which are connected to the ear via a long tube(internally). Such symptoms will often go away on their own unless you develop infection in the ear and the internal tube(Eustacian tube). That may require a visit with an ENT specialist for antibiotics or other medications.
