I would not worry about it UNLESS you develop any other strange symptoms. The tingling could mean something (I don't know what), but I don't think doctors will take an isolated paresthesia seriously until and unless other stuff starts happening. Doesn't sound like tinnitus to me, either! Tinnitus is NOT tingling.
Keep your PCP informed of any new symptoms. If you get any other significant ear or face symptoms, you may need an MRI and maybe a neurology referral, but hopefully that won't happen.
If you suffer from tinnitus there are probably many possible causes. Hopefully it will go away.
I'm only suggesting that you look into allergies because (a) it's easy and (b) that was the cause of my tinnitus, but I had worse symptoms too.
I suggest you check for standard type-1 (IgE) allergies to food and your local environment, that is a possible & likely cause of such mild symptoms (worst case, see my Journal entry and web site link on type-3 (IgG) food allergies which was the cause in my case)
