I sweat constantly

I'm a 72 year old female. For the last 10 years I am always hot, always sweaty. It's getting me down. In the summer I can at least wear loose lightweight clothes and still look decent even with my stupid fan around my neck. But every year when it cools off I am in despair. I always look like crud. I cannot wear a cute jacket or sweater. I cannot wear a cute coat. My makeup sweats off. My hair looks awful because of scalp sweat. I am so uncomfortable. I believe it to be a med I take for arthritis, but I absolutely have to have it. I'm not really looking for solutions. I wonder if others have the same problem.
