Suggest Treatment For Inner Ear Infection And Vertigo
Investigation is needed
Detailed Answer:
vertigo needs some time to get better. If you have taken antibiotic treatment for the infection then you just need some time.
Unilateral leg swelling and chest pain requires urgent investigation for serious conditions like deep vein thrombosis and pulmonary embolism. Your age and the lack of any important medical history (you haven't mentioned any problems) is against serious diagnoses like the aforementioned ones but they have to be excluded. Visiting the emergency room is the right next step for you.
Contact me again if you'd like more information. You can also provide more details regarding your symptoms (when did they start, describe the pain and its relation to the respiratory movements, any associated symptoms, etc)
Kind Regards!
