red sore bumps

Okay so i dont really know what to do, like a week a go i noticed a red bump on my finger that felt like i had a sliver in it, but i did not have one.
Well now it seems to have spread I have them on both hand just on my fingers its really weird.
They just feel like little slivers in the red bumps idk what it is and the only thing i have started doing is tanning, i dont think that could have started this,also i have the bumps on one toes its just weird I have never had any skin issues in the past, I do know that any cream i put on it does not help so i guess if it gets any worse maybe i should go to the doctors :(  does anyone els have this issue cause i have no idea what to do
