Lately, I've had this vertigo issue. Anytime I tilt head back and turn to the right side or while I'm lying down in bed turning to the right, sensations of vertigo starts. It starts off with a feeling of lightheaded to dizziness and a few seconds of the room spinning and then it stops.
The left side is not affected at all.
Moreover, every morning, no matter how well or long I sleep for, I'd wake up very lightheaded, like the feeling of being tipsy from drinking although I hadn't been.
At random moments, tinnitus happens in the right ear.
What can be the underlying issue? What can I do?
There are a couple of underlying causes of vertigo, with the vertigo itself being caused by phlegm. You should read more on the 1st half of this article on vertigoExternal ↗. Since you mentioned tinnitus, I am guessing it is likely a kidney issue. However, there is a liver cause of tinnitus as well. You can differentiate them through this article on tinnitusExternal ↗, under the "Chinese Medicine View" tab.
These articles should give you a better insight on the issue, and it should enable you to think about your lifestyle factors from a better viewpoint. Thinking about those factors, please list:
Sleep time and quality:
Digestion quality (any bloating, heartburn, poor appetite, loose stool, etc):
General breakdown of diet:
General yin/yang balance, do you feel wired/anxious/can't sit still/hot, or do you feel sluggish, lazy, cold, etc:
Appearance indicators, such as undereye bags/discoloration, dryness, pimples, redness, nail/skin quality:
Any headaches or other symptoms of discomfort:
This will further breakdown any imbalance in the body. From there, I can advise you on certain lifestyle choices. As far as direct treatment, you can order herbs or do acupuncture on yourself, however seeing a TCM clinic would be the fastest option here (as well as having a paid clinician able to tend to you).
