I used to have an ear ache and it went away when Jupiter went behind the Sun, The guy down the street had a car accident, a Solar CME hit the atmosphere, the TV station I was watching turned to a commercial....ect.... Your phone could have had it's volume turned up too high, you could have been pushing against your ear too hard, using it at the wrong angle to your ear, out gassing of the plastic and adhesives, and many other possibilities. There is a stronger field with headphones than with a cell phone. So if nobody has problems with a set of head phones then there's no problems with cell phones.
I use to get really bad pain in my ears from my cell phone, since I stopped using it, well i mean since I broke it 6 months ago, and haven't had time to purchase another one, my ears feel great and back to normal.
First, Read up on Radio Communication and Antenna construction. Even just one book so that you have at least the basic idea how "radiation" works. Next, grab some generalized reading books on quantum mechanics/general relativity/electromagnetic spectrum/ect... all with getting a very basic Discovery Channel style education and you will see that the radiation from cell phones is nothing compared to the radiation you get from other "Natural" things. I.E. the reports you hear about Cell Phones causing health problems is nothing but the uneducated being taken for a ride. Or, the uneducated being told the Sky Is Falling. Toss a penny against a wall, It releases a tremendous amount of energy. Toss an ICBM against that same wall and it simply rapidly fall apart. Which is more believable? Both are correct but the penny situation sound worse and will get people screaming about how dangerous it is. Next, There is far more radiation coming off that light bulb above your head than the cell phone.
With those same books you'll begin to understand that "having a thumping sound" doesn't tell us much though we can guess what you mean, maybe. Does this thumping sound thump with the heart beat? Does it follow with each movement of your eye ball? You mention loud noise, Is the loud noise generated outside your ear or inside? There is a muscle that tightens up your ear drum to help protect the ear system from damage from loud noises, could that "thumping" be more of a vibrating sound from the voluntary movement of that muscle?
