Brief Answer: Needs complete clinical correlation Detailed Answer: Thank you for asking! Dizziness after age of 40 is so common that every second person presents this way.Its causative agents are too many and it needs an expertise of otrhinolaryngologist and neuro otologist to sort out the cause with help of Auditory, vestibular, complementary blood and radiologic tests help in narrowing the differential diagnosis and tailoring treatment. Simple flu and anxiety depression can cause that too. So can the headaches and migraines.many over the counter medicines to herbal remedies also cause that. As you recently quit smoking it itself is the major contributing factor to vestibular imbalances due to withdrawl effects. It needs to be evaluated in detail for sorting out whether it is due to peripheral or central causes. Peripheral causes are BPPV, vestibular neuronitis, Ménière disease, and immune-mediated inner-ear disease. The most common cause of central dizziness is migraine, frequently referred to as vestibular migraine or migraine-associated dizziness. Other central causes include demyelination, acoustic tumors, and brainstem or cerebellar vascular lesions. Most of these dizziness spells self resolve in 6 to 8 weeks. All you need is safety measures and vocational rehabilitation to avoid any dizziness induced falls and trauma. Simple steroid drops, betahistidines, meclizines and some amoxicillin antibiotics, vestibular suppressants, antiviral medication, and antiemetic medications will help. You need to seek the otorhinolaryngologist and otoneurologist for a detailed examination and a complete clinical correlation. I hope it helps. Don'"t forget to close the discussion please. Take care
