What are possible causes of red bumps on my uvula? (photo)

Thank you for your question. The throat (oropharnyx) has a pink lining (mucosa) and numerous minor salivary glands underneath it. Most commonly the lump at the back of the throat is a benign cyst (collection of mucous or saliva). This usually occurs due to some injury or irritation to a minor salivary gland that has caused saliva to be trapped under the lining of the throat. Rarer causes of a lump at the back of the throat include benign or malignant (cancerous) tumours from the mucosa or minor salivary glands.

Thank you for the question. Unfortunately, I think the picture is not clear enough for a proper assessment. In general, if the bump is due to a pimple, it will come and go and is not usually persistent. A cyst or a malignant growth is usually persistent and may slowly increase in size. It is best for you to see your doctor for a proper assessment if the bump is persistent.
