What Do Itchy Bumps On The Hands Indicate?

I have weird bumps that have appeared on my hands when I itch them. They are like clearish bumps, and if I scratch enough because they are super itchy I can make the bump disappear and raw skin is left. Usually there’s not that many, but right now one side of my ring finger is full of them. And two days ago when I was doing dishes, this is probably unrelated, but I had a strange pain in my left hand and since then my left hand has been a bit painful to bend and stretch and quite itchy and now there’s a lot of these bumps and it’s so itchy. I was wondering if you have any idea of what it could be? (I did just get over an over week long supposed bacterial cold that I was prescribed antibiotics for. I woke up with a sore throat on 1-26-18, symptoms have changed and I’m a lot better now but still have mucus and not feeling 100% yet and it’s february 9th).
