Hi, You may still have remnants of an upper airway infection such as sinusitis which is why your teeth may be tingling. However, other symptoms could be due to the respiratory condition due to deconditioning or mild reactive airway problems such as secondary bronchitis precipitated by your sinus infection. Dizziness could be from lack of proper hydration and so you may try drinking plenty of liquids or it could be from any medications you may have been prescribed or taking over the counter. Body aches are typical of viral infections that accompany any type of cold or flu. You may try nebulizations for the breathing, generous hydration, and if the tingling in the teeth persists to see a doctor for a possible review of your sinuses. You may require a different approach to treating this if it turns out to be a bacterial infection. Hope I have answered your query. Let me know if I can assist you further.
