It sounds like it may have become infected. Do not remove your earrings but try to swab the area with an alcohol soaked cotton ball several times a day- front and back If this does not reduce the swelling within a few days you should have a doctor look at it.

Bath your ears in a salt solution, on the contrary to oppinions it doesnt actually sting at all i would say but for calming your nerves use a light salt solution then when your confident its not so bad use a heavier one (by salt solution; fill 1/3 of a mug add boiling water to it and let it cool down a little then just add salt )use a que tip to put in on (diffrent one per peircing). make sure you wash your hands befor touching the peircings you should be turning it round about 3times a day so it heals without sticking to the peircing, a slightly blocked feeling in an ear after cartilage feeling is normal but if they hurt like a full ear ake or you see puss then thats an infection, so it needs to come out and wash it with strong salt. Dont use TCP its to strong and will dry out your ear/skin & sting lots. Some pain, swelling and redness is normal though -its a wound- especially when hair catches it. personally i dont think ibroprofien or any pain meds is a good idea you need to monitor the pain & influation to know if its getting infected, thats part of getting a peircing a bit of pain
before hand i would not have advised you to get a cartilage peircing on both ears at the same time as you see C-peircings can easily take a year to stop being sore when you knock/lie on them so if u sleep on your side then yes it will be sore and that ear will be more swollen in the morning so as you have new ones in both ear sleeping on any side will be sore! it will be bit better by a month and then more and more better slowly. Its safe to change C peircings after 6/8 weeks some say 10, be carefull with what peircings you use, tho cartilage peircings are less problematic to types (ie nickle,silver) as its the flesh that reacts, but it will likley still hurt for about up to 12-15months easy

I have 3 carilage peircing (11 on my ears total, tounge twise & navel) so i have some idea what im talking about but im not a professional. If your worried about the infection go to a doctor, SALT is good though, sorted all the ones. I had an infection once first time i had my thirds done (both holes)i took them out & re-did them about 3months later -so 13times-.

Seriously NO ALCOHOL!!! do not use peroxide either. Salt water is your friend. A lot of piercing shops even have the nice little spray bottle for that. I have 15 piercings and i also know what im talking about. Alcohol or stuff like it will eat way the healed part. If it's not discharging thats whats causing the bubble. ITs not infected yet necissarly but working on it. The salt water will break that gunk up and get it out. Look onlie for the spray if a store near you doesnt have it. it's soooo much easier than sticking your ear in a cup for 10 mins. I have a doth peircing (a weird ear thing) and thats all i used and it healed perfectly. The stuff is call H2Ocean. When i was 12 i got my nose pierced. It got pretty bad as it was my first non ear pericing and i did use a q-tip with a dab of peroxide just one time and it helped. If it really wont go away try that just once though.
Hope this helps...really look up that H2Ocean spray though its awesome stuff.

oh yeh i used the H2ocean stuff before too ages ago tho, forgot Very good stuff , out of curiosity what is peroxide/whats it do? i always thought that was to do with hair dye/bleech, think thats how i got dark dye out onece. sapose that would deffinatly work if its safe for skin :S lol
