@Ranga me! I am so glad that you mention this. I have a lot of symptoms on the left side of the body. And noone knows what is that, some doctors said this is not related to POTS, some that it might be. And all of my tests are fine. I feel like something is pressing on my left side.
Here are my symptoms:
pain and pulsing sensation by the left ear (left side of the face). Like something is standing there and is pressing something, especially when I am eating, talking, laughing, moving my eyes... Pain is spreading to the left front side of the neck with some nodules and itching. Sometimes pain is going to my left side of body - arm, thorax, leg and some spazms also occur.
Sometimes my left side of face is red, like it is burning inside and is little swollen. It reacts usually to heat but it's not the rule.
I have crackling and fullness in my left ear; with moving, sounds, swallowing; there is also no rule. All these symptoms started along with POTS symptoms.
