My sinus allergies is killing me. So much pressure the left side of head. Left ear hurts/burn sensation. Legs/arms feels like its vibrating any relief?

Nasal allergies. Warm shower and staying in steamy bathroom will help. Can use nasal saline washes several times a day to wash out the allergens. Use of an over-the-counter antihistamine can help. If not relief with these, then you need to see a doctor.
