What Causes Excessive Sweating In Axillary Region?

I am an 18 year old female and I am experiencing excessive sweating in the axillary region. I have been researching hyperhydrosis, which seems like it would fit my condition. I do have hormonal issues which could contribute to the issue. However, I have already been consulted by two physicians in person. The first prescribed me a liquid topical solution which I applied to the underarms (cannot recall the name). Although the solution seemed to alter the amount of sweat, it caused rash and scabbing. The second doctor believed sweating is normal in teenagers. However, I am not comfortable with the amount of sweat I produce. I cannot wear clothing that comes in close contact with my underarm, and I even sweat when I am not wearing sleeves. I can feel/see beads of sweat running down my arms while sitting in class or watching TV. I sweat all day and am not comfortable in my clothing. Is there anything I can do? What can I specifically tell my doctor so he notices that it IS a problelm.
