@Ray552 You have mentioned "I started experiencing numbness all over my body, my whole back, neck, legs, and even my face to the point where I cannot feel normal sensations." "I would also like to add that sound causes pressure on random parts of my face and tightness, what my question basically is whether all the numbness etc. can result from an acoustic trauma or could this be something else?" You also mention your eyes and neck.
You may have developed a parasympathetic nervous system reaction. Read the second paragraph in link starring with 'Nerve fibres'. Look at the blue highlights including the facial nerve- facial muscle tension that discusses the tongue. The facial nerve associates to taste and numbness and that can cause hyperacusis, but often is temporary to possible associated conditions. Can not say that another condition may have involvement. Your audiogram looks pretty good.
