Night sweats -please help!

I am 30 years old and suffering from night sweats for last 2 years. I tried my best to explain below my medical conditions as i cannot tell if this is a serious condition or a side effect.

For night sweats I had many hormonal tests, checks on lungs, hearts, kidney, liver, full check ups but unfortunately no specific cause have yet been found. That is frustrating as day by day it gets worsen. Everyday early morning i wake up in full sweat from head to toe and shivering.

On top of everything im having mild headaches, not easing with pain killers. Once starts goes on all day, generally on right side of my head around my eyebrow.

I am on 150mg Lustral for th last 6 months as i was diagnosed by depression. For the last 8 years depression comes and goes, this is the second time since then I felt i need help.

Also im on contraception pills for 3 years.

I am very frustrated that my gp could not give me any reason for night sweats. I am hoping someone out there may have same sort of symptoms or using similar medications.

Sometimes I notice one minute I will be very very hot then the next very cold like shiver cold. I am on Plaquineil but I really dont think its from that as I had this issue prior to starting.
