I have this weird itchy red/bumpy rash, that has little zit like bubbles. It's from my thumb to mid way to my elbow. What could it be???

Rash: I'd really need more information about acuity/chronicity as well as associated symptoms - pain, drainage, size of bubbles - to hazard an educated guess. Could be contact dermatitis from something that touched this part of your arm. Could be shingles. A Dermatologist should have a look at this.

Too little info: Most skin rashes need to be examined in order to offer meaningful insight. In the case of a reaction, a discussion about potential exposures is also necessary.

My boyfriends thumb is red swollen but he doesn't have any open cuts or acute injuries to it. Swelling/redness is spreading. Is this contagious?

No: But it sounds like an infection that is getting worse. Have him checked very soon, it sounds like he needs antibiotics and potentially a tetanus shot. All the best.

Sound Infected.: When was your last tetanus shot? If it has been > 10 years ago or you don't know - should be repeated. At this point, medical assessment of thumb would be prudent.

Many things: Is the area round? Raised? Itchy? Scaly? Most commonly, this could represent allergies or seborrhea/eczema. Duration and associated symptoms/findings are necessary to further delineate. Best is to have it checked out if you're worried.
