Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain pain in ear along with
redness in external ear and a recent history of cold points towards
ear infection and the symptoms seems to be due to it..
I would however suggest you to consult an Otolaryngologist and get evaluated and a thorough clinical evaluation and otoscopic examination can help in diagnosis and treatment can be done accordingly..
In case if there is infection, you can be advised to take a course of antibiotics like
Augmentin, anti-inflammatory painkiller like
Ibuprofen, and also put antibiotic and
analgesic ear drops..
You should also avoid excess water exposure to ears like swimming as it can increase infection..
Avoid picking the ears..
Hope this information helps..
Thanks and regards.
