Fainting

katie
So I've been a fairly frequent fainter mostly as a child, but now the last 18 months or so I've either fainted or had the symptoms (cold sweat, black static vision) every other month or so? I hesitate to see a doctor (high copy and don't really like my doctor) esp when as a kid nothing was ever found.
Does anyone have experience in this? Just for more data I'm 30, not overweight but should lose some weight given my small frame, very good diet, minimal exercise, no diabetes or other health issues.
