Before looking at getting sweat glands removed, you should firstly look at your diet.

I remember a woman having the same problem and noticed it developed when she ate meat.

Try eating fresh fruit and vegetables, give up meat, dairy, wheat and Sugar for a week and drink plenty of water.

Try for a week and see if it makes a difference.

also get your armpit checked for fungal skin infection, but I have a feeling the change of diet might help.

Good luck
