Went to the GP but..

Hi all! So about a week ago I started feeling lightheaded. This was accompanied with a few heart palpitations. I was worried because that never happened to me before and I visited the hospital where I had an ecg, blood pressure and stethoscope testing. Everything was clear. I went to the gp and explained him the symptoms and he arranged a blood test and a 24h monitor for the heart to check these heart palpitations. Thing is I feel this diziness almost all the time and the blood test is at the 7th of november. Few nights ago I was sweating while in bed and I also feel fatigued sometimes. To explain this diziness of mine better, it feels like my vision, apart from the thing I'm looking is kinda blurry but it's not. I can still see clearly. Also, I feel my head kinda heavy. Any guesses what that is and how can I prevent this diziness? I don't wanna live the next 2 and a half weeks like this.

Forgot to mention, I'm 21 and quite healthy overall. No drinking, smoking and drugs and not obese.

Hi I’m only 15 and since yesterday my head kinda feels heavy and I’m lightheaded, a couple days before I had a really bad cold and conjunctivitus and it was really bad and that’s stopped now and that’s come. I’m really worried I don’t eat healthy I have recently but it just worries me I know I’m not answering any of your questions but I’m just so worried cause I’m only 15 and a boy. 

I have some of the same feelings and it is a horrible feeling not knowing wats wrong I'm having a MRI and a Ct scan on tomorrow hopefully I'll know then cause this dizziness and headaches is horrible feel as though my head is heavy as well hope that you feel better though

Try not to freak out. Look at SCM trigger points on the net. It could be your SCM muscle which is in your neck.

Yeah I had already had a X-ray done and she said I had a little artistis in the neck area and muscle spasms across the top of my shoulders but the back of my head is real uncomfortable and my neck I can't comb my hair or touch my head it just feel heavy but most of my pain is in the back of my head and neck area the most uncomfortable area and lord forbid the headaches is awful and I can't sit up or stand up long before I get real dizzy I gotta lay back down lord hamercy I been freaking out I shoull hope it isn't nothing serious thanks for responding back though
