Thyroid cartilage

Hi guys.

I am a 23 year old and I am very scared. I have a diagnosis of lyme, with many neurological symptoms; vertigo, tinnitus, fasciculations etc ... Articular pains, crunches etc ... The fact is that yesterday I touched the thyroid cartilage, coinciding with the creaking of the joints, knees, elbow, wrist etc ... and I noticed that the The left side is much larger than the right side and when I move my neck from one side to the other, if I put my finger on the cartilage I notice a click. I am very scared because I think that I did not have it before, and I have found a disease that can explain all this. Recurrent polychondritis ....
Is it normal to have an asymmetric side?

thank you very much.
