Skin bumps and cysts are quite common occurrences on your skin. Though it's a good idea to get it checked if you are unaware of what's popped up suddenly, you must also understand the difference between cysts and other types of skin bumps. Read this guide that has comprehensively explained both cysts and skin bumps. What are cysts? A cyst is a fluid- or pus-filled small pocket that mainly occurs due to an injury, infection or other issues. In most cases, they appear benign (non-cancerous) but if they show signs of trouble, it's best to get them treated. Yet, untreated benign cysts can cause serious complications, including blood poisoning. The cysts tend to pop up anywhere in your body or at least under your skin. What are skin bumps? Skin bumps are abnormally raised areas that include lumps and swelling and often their causes lead to different symptoms and treatments. Almost everyone gets skin bumps at some point. They come in all shapes and sizes and most of the time, they are harmless. Most skin bumps are benign, temporary and will go away on their own, while others are permanent but again harmless. Only on rare occasions do these skin bumps appear to any underlying health condition, such as skin cancer or infection. Especially if the skin bumps start changing size, color or shape, it's crucial to get it checked. Cysts vs. Skin Bumps Cysts, the sac-like structures, are found under the skin and filled with fluid, air or other substances. On the other hand, skin bumps are a broad term for any raised spot on the skin that includes pimples, warts, moles or allergic reactions. Cysts appear smooth and round and they grow over time. They don't hurt or cause any discomfort unless they are inflamed or infected. If you are removing the cysts, then it's essential to follow cyst removal post care instructions, such as keeping the area clean and dry to get it healed quickly.
