Hello. I have dime sized red rumps in various different places on my body. Not in clusters. Some of the bumps get to even being a nickle sized in a couple places. My bed is Brand new. I ve had it less than a month. I checked every part of it for bed bugs, and I believe the cause may be flea s. As the blankets I received from my Grand mother s house, we re down stairs where her 2 Cats spend alot of time. Although, I ve never seen any of the insects leaping about. I just know that every time I lay down to go to sleep. I wake up in the morning with more bumps. As far as I can tell. No other bumps appear during the day or when I m up. I merely wake up, and find that more are there. They are extremely itchy, and I believe after scratching them enough. Have clear puss coming from them, If I accidentally scratch too hard. I hope I ve provided enough sufficient information to help with this diagnosis.
