Little red spots originated from foot
A few weeks ago or a month ago, I noticed small pin point spots on my foot, they started in small dots and became clusters, and I thought it was petechiae at first, cause it looks exactly like the pictures i've seen. It started getting to my ankle, and then my legs, and now thighs and hips/stomach area. The ones around my stomach are a bit bigger than the ones on my foot. I looked up information on petechiae and it says they just brown and fade after awhile, and the ones on my foot have started to brown and very very slowly fade, but I still have it everywhere else. It also looks like they're just starting to appear on my arms.
Any information would be good, I don't know if I should see a dermatologist about this or just wait for it to get worse or better. I've been putting lotion on it daily and drinking a lot of water incase it has something to do with the weather.
