Profuse sweating but only on abdomen

Hello. I'm new and would like to ask a question. I have been experiencing profuse sweating on my abdomen almost every morning after my shower. The sweating is worse just beneath and between my breasts and I literally get rivulets of sweat that run down my stomach. The rest of my abdomen just sort of gets moist and sticky with sweat but between the two I end up with lots of sweat. I also seem to be experiencing sweating of the groin that occurs everyday and peaks during the noon part of day. I don't sweat anywhere else. Not my hands or feet or anywhere on my face.

From the research that I've done I know this is called Hyperhidrosis but I don't understand the cause of it to well. It started around the first week of August and I attributed it to the very warm and humid weather at first. But it's still with me and the weather is now much cooler and it only happens after my shower. I can be fresh out of the shower walking around the house in my pj shorts and a t-shirt with cold wet hair but my abdomen will just be dripping with sweat. Then within about 20 minutes it stops.

Does anyone here know what conditions or diseases could cause Hyperhidrosis to appear like this? Can this happen with MS? Or does anyone here have personal experience with this?

Sweating is a response of the sympathetic  nerves.  Hyperhidrosis is is common on the feet, head, axilla, but not as common on solely the abdomen.  Sweating is typically controlled by the hypothalamus (a region of the brain.)  So, in theory, a lesion on the the hypothalamus could effect the  sympathetic nerves to the upper abdomen and cause excessive sweating.  It could also be the result of anything that could have an effect on the sympathetic nerves controlling the sweat glands in the upper abdomen.

I don't disagree with Bob, but it would be unusual for the lesion on the Sympathetic Nervous System to involve those areas so symmetrically.

In short, we can see isolated areas on the body that sweat more or less than normal.  When they involve the typical, "sweaty areas" is is less likely that MS is involved.

Thank you both for responding. I looked sympathetic nervous system up on Wikipedia and see that goosebumps and high blood pressure are also affects of the sns when it's stimulated. I have goosebumps all the time lately and am being treated for high blood pressure that showed up in August. It was 150/101 Monday during my appointment. But the reason I think it was so high is because the wallpaper in the exam room was driving my eyes crazy. It was making me so dizzy that I had to keep looking down at the floor or the door to avoid feeling like that. And I've never heard of such a thing and felt like I was going loosing my mind. I tried to tell my neuro there is something going on with my eyes but....no go. Anyway..I know it sounds crazy and really off the wall but I really think think the wallpaper making me dizzy is what made my blood pressure so high that day.

My blood pressure has been on the high side since August though, just not quite that high.

But heck if I know what any of this means. My neuro is treating me for the high blood pressure but has said not a word about trying to figure out why it's so high. And he doesn't think anything about the abdominal sweating. So I feel like I'm on my own as far as figuring things out goes.

All I know is that my body seems to be going haywire with all kinds of funky little things going on. None of it is debilitating, but none of it is normal either. I just want to understand what my body is doing.
