Dizzy spells in exercise

For around 2 yrs i have been suffereing from neck and back problems. where by if i click my neck it relieves it for a short period. This dull pain is constant and does not go away. i often have to sit down at work after 20 minutes standing because my back aches. i went to a physiotherapist and they told me that i had "over mobile joints" and my neck clicking was caused because my shoulders had weak muscles and werent strong enough. since then the clickin and aching has moved to my lower back and groin/hips. the pain sometimes is uncomfortable but is bareable once i have clicked it. But recently i have joined a fitness club, i am young and relativly fit and can join in easily with all activities, the first time i went, we just began the arm weights section, where by we lift weights in differnt directions and timings, after around a minute i became feeling dizzy and causing my earring to fade and nearly blacked out, consequently having to sit out for a bit, i just put it down to not done that much exercise for a while. but i went the next time it happened again but worse, iv read some different sites and they put it down to, lack of oxygen, lack of food, lack of water etc. but i eat before i go, always have a bottle of water, and my breathing is fine. I find it odd that it is only when i lift my arms. Does anybody have any idea why i am feeling faint? and if they think it has a connection with my neck problem?

any ideas would be appreciated..

thankyou

Hey

Everything you just said is exactly the same type of problem I am having and my neck is absolutly terrible. I was infact drunk one night about a year ago and collapsed on the bathtub...'silly really. But a year on im still suffering from wiplash and i've gone to see a physiotherapist who started clicking my neck into place, but the cost was too much and couldn't afford too much therapy. I was overweight and he told me to start exersing (i was 19, 16 1/2 stone). When I started exersicing I experienced the same thing. i had a bad neck and there was a type of sensation that came across the leftside of my skull and made everything so tight. once I stopped my run i got that dizzy experience all the time and i had to focus not passing out. To be honest my neck is pretty bad and i get bad vision in my left eye to from the neck and such a tightness across the skull, like a rubberband being stretched across it. I got so irritable, but i found i just had to keep on running and getting on with it. I know it hurts but before everyrun I do, i have to stretch my neck and jaw, rotate my neck and kinda snap my neck in place, which feels got for about 3 seconds and then gets tight again. I still get those feelings but i find i just have to get on with it, im now 20 and weight 12 stone. I just feel you probably need to have some more treatment for your neck, which I really have to but cant afford. Just keep on running and try to stay conscious, thats what I do. Silly really, but i see a result in my wieght!?!
