Hi. Thanks for the query. Swelling of tongue can be most probably due to allergic reaction causing allergic angioedema of tongue. Other causes can be accumulation of Amyloid protein deposits on tongue, hormonal imbalances, side effects of medication etc. So first consult an Emergency room and get evaluated. If there is any doubt then a blood test can be done to narrow down the exact cause of the swelling. In case if it is due to allergic reaction then it will be ruled out by an allergic test, and you should avoid exposure to allergen. If at all you get exposed and there is swelling anti allergic and steroid shot can help in relieving symptoms. If it is due to other causes then they will be treated once the cause is ruled out. Hope this helps. Regards.
