I have quite a wide range of symptoms, but I will try to make this short.

Around six weeks ago, I awoke feeling lightheaded and dizzy to the extent I was anxious and suffered a faster heart rate, shortness of breath, shaking, feeling very cold and looking pale. I visited a doctor and after an examination was told that my symptoms were very similar to pre-fainting, and that it might have been brought on by stress. However I was advised it was not serious.

After a few days of rest I felt again. However about 2 weeks ago I started to suffer headaches in the temple and sinus area with stabbing pains lasting for about 10 seconds in the back of my head also.

Then three days ago I awoke again to a milder version of what I suffered the first time, and because of the shock the first time (i am anxious of fainting as I never have before), I began to feel anxious with again shortness of breath. The past three days following on from this, I have been restless, losing sleep at night but feeling very tired during the day.

My symptoms have not completely stopped and as I type this I still have a sharp pain in the left temple.

Note: I have a small, hard lump around the size of a pea just above the hairline on my left temple, I have never consulted a doctor as I have been reassured by family it is probably a hair follicle. I have had the lump for years and it has never caused me trouble, but I was just wondering if it might be related.

Thanks for any help! (ps: I am a teen, if this helps at all.)
