I have small bumps on my face and neck what could it be?

They are probably small blisters from the sunburn. Use gentle cool compresses to reduce the heat. Apply aloe vera gel if you have any, and if you don't it would be a good thing to get someone to pick up some for you, or some other gel especially for sunburn. Take an appropriate antiinflammatory pain medication if you need one. Rest as much as you can for a couple of days until the burn starts to fade. Drink plenty of water as you are probably still very dehydrated.

Vinegar is an old remedy to treat pain from a sun burn. Place some in a spray bottle and dilute it with some water. Then spray the affected area.

Apply a topical pain relieving spray or a lotion that contains lidocaine, to lessen discomfort.Do not use spray near eyes.

Apply a milk and bread compress.Soak slices of white bread in cold milk and apply to the affected area.The cold milk will draw heat from the area to cool the skin.Whole milk is best, as the fat in the milk is said to lubricate the skin and help it retain moisture.

Definitely stay out of the sun for a few days.

As your sunburn begins to heal your skin will begin to peel, and this will likely cause itchiness. Calamine lotion will help to soothe the itch that accompanies a bad sunburn, and keep you from clawing your already tender skin to shreds. Watch for blisters and do not pop them if any appear. They protect the tissue underneath. Be very gentle with your skin as it starts to peel in a few days. Use a gentle moisturizing cream on the peeling areas.
