Is thyrotoxicosis only affect on female? How bout male.

And, is "bounding pulse" relate to thyrotoxicosis? Recently I have this weird symptom. I felt like certain spot of my body will pulse, just like heartbeat. I can see it clearly from my skin is beating. It happen spontaneously, all over my body. Is this a symptom of bounding pulse?

I am experiencing weight loss last couple of years. As I surf online, I realize that this two symptoms "thyrotoxicosis" and "bounding pulse" match closely to what i'm experienced. Til today I can't put on weight no matter how much I eat.

Can anyone advice on which specialist I should check on?

Thanks
