How are you now?
I haven't experienced ringing myself, but lately I've had some stinging pain in my ears. It comes and goes (like evey pain related to VDD does for me...), often it's the right ear but sometimes it's the left.
I relate it to the D-deficiency, and my doctor says that basically every organ/system could be troubled by the VDD.
Back when my numbers were low, I did have some ringing/buzzing/humming in my ears. It was such a long time ago that I had completely forgotten about it. No one said it was related to the VDD, but now that my numbers are in the "normal" range I haven't noticed it. Granted I seem to always have some noise in my ears, which I notice when things are very quiet. Let us know when you get into normal ranges with your D and if you are still have the ringing.
I too have some ringing in the ears... Not too bad tho. I'm concerned that you are only taking 1000 iu. 10.3 is very low. 10k iu/ day for several months would be more likely to raise your levels.
D3 is more easily utilized by the body than d2 it should be noted. Also make sure you are taking magnesium daily and getting at least 1000 mg calcium in your diet.
