I Have Suffered From Stress Recently But I Overcame A Lot Of Problems Now I Am Getting Clicking In My Left Ear And Also Headaches , Could This Be Due To The Stress Or Could I Have Damaged My Ears As I Work With Earphones On ?

You say you work with earphones on, is it to listen to music, dictation, or to keep outside noises to a minimum (like in a factory)?

Stress can cause headaches which can also cause a clicking noise or sensation. However, I suggest you see an ENT (Ears, Nost, Throat) doctor to rule out any permanent damage.

Does the clicking mostly occur when you talk or chew? Do you have a history of nasal allergies or ear infections? If so, it could be due to a 'floppy' eustachian tube and may respond to a course of decongestants. The headaches could be due to associated sinus problems.

Another source of 'clicking' could be due to a TMJ (temperomandibular joint - the joint where your jaw pivots) problem. TMJ problems are aggravated by stress and can indeed lead to headaches. In either case, see an ENT as advised above. If you think you might have TMJ problems, a visit to your dentist may be indicated too...

As mentioned elsewhere (on this site) I think it could relate to Vitamin B12 difficiency.
