Dizziness / Lightheaded, Prominant Veins and Twitching Muscles

Two months ago I started to feel dizzy / lightheaded and it has persisted almost constantly ever since.  About a week after the dizziness started I began to get headaches too.  I am 23 years old with a healthy heart and ears that are free from wax build-ups (ruling out some potential causes).  Around the time that the dizziness started I felt difficulty in breathing, but in my nose not my chest.  This has recurred occasionally since.

About 4 weeks ago I felt weaker in the hands and arms and following this my veins in my hands and arms began to become very prominent - both in color and in coming to the surface.  They also sometimes tingle and/or throb a little.  About 2-3 weeks ago my lower legs and feet developed the exact same problem.  My job requires a fair amount of walking each day and I now find my legs feel in more pain at the end of a day than they used to.  

Around the same time I started to get brief but frequent muscle twitches.  These occur mainly in my hands, arms, legs and feet but have also occurred just about everywhere else on my body.

Around 2 weeks ago the dizziness and headaches stopped for about 4 days only for the dizziness to return, although so far the headaches have not.  I have tried decongestants for my sinuses and although that has helped the breathing it has oddly made me more lightheaded.

This is causing quite a lot of distress as until recently I have always been in generally good health and then all these things come along at once.  I am convinced that some if not all of these symptoms are related but am without much of a clue as to the cause(s).  Any ideas?  Any help is truly appreciated.

Hello Dear,
The key causes that lead to dizziness are;
- Sudden drop in blood pressure or dehydration which may inhibit blood to the brain causing lightheadedness.
- Dizziness may be accompanied by various disorders such as: allergies, hypoglycemia, common cold, fever, diarrhea, vomiting or flu.
- Loss of balance or spinning sensation may be related to a malfunction in at least two of three main organs that contribute to our sense of balance: inner ears, eyes or the nervous system.
- Serious disorders that may cause dizziness are: stroke, heart attack, severe drop in blood pressure.
