Hi, thanks for posting your concern in HCM. Loss of concentration, tremors and shivering suggest a provisional diagnosis of Anxiety
disorder. The ear problem and headache may be due to panic attack
or some pathology in the inner ear
or upwards. To rule out, any neurodeficit you need to consult a neurologist
. An ENT surgeon as you said had diagnosed SNHL and that may be due to pathology in inner ear and requires treatment under ENT specialist's supervision. For any further query, you can write back to us. Best Wishes.
