I have multiple sounds in each ear. One of my loudest sounds may be somatic (muscle induced) though. I have multiple health conditions and one of them is TMJ dysfunction and myofascial pain syndrome. I've got some weird face numbness that comes and goes below the eyes and also weird cold water sensations and burning all over my body.
Well, my right masseter muscle hurts a lot. When I press on it I get a loud hissing in my right ear that lasts for a while after, it doesn't do that on the left side, which doesn't hurt. The right is the one that normally has a hissing or high pitch hissing.
Trigger points in the masseter muscle can cause tinnitus, as well as the SCM muscle and maybe others, almost a dozen according to some lists. I've tried treating my TMJ issues without luck and also tried massaging the masseter muscle, but the pain always stays or returns soon and the sound never goes away.
I recently discovered a trigger point spot in my upper part of the SCM which when pressed just right refers pain to the masseter muscle area somewhat. I have also read that the SCM trigger points can be the trigger of the masseter trigger point, so I may be able to treat the SCM trigger point now that I have found it. It was a small spot that was between the two divisions and I can't tell which. It is very hard to massage myself and keeps jumping around like jelly. It is hard to use two hands as well.
When I put my head down on my pillow in a suburban house at night that is when I can hear a lot of different sounds I didn't used to hear. I can't hear all of them in most environments or in my apartment in the city. My left ear makes some kind of beeping noise I can hear during the day. The other noises are lower tones I think and not as loud.
I used to think I just had this one somatic sound on my right side and it would get better when I fixed my trigger points and TMJ, but after discovering all these other sounds I got depressed because I doubt they are all somatic or can be fixed.
My tinnitus onset coincided with an adverse reaction to a medication / poison as well as the muscle muscle problem progressing from just chronic neck pain at the base of the skull to then intermittent face numbness below the eyes and temple and jaw pain and electric shocks in the side of the head.
After that I tried to treat the trigger points, but my massage therapist referred me to a private doctor for other tests and he used a non-approved test for lyme disease and said I had it. I then used a lyme disease organization referral page and tried antibiotics from a doctor there and developed my third health problem when I started the antibiotics. Since then I've gotten cold water and burning sensations all over.
No idea if it could all be related, but I'm not assuming it is anymore.
