[|Human|] Within a hour s time a very large lump appeared on the right side of the shin bone. it s larger than a grapefruit. Not painful or red or warm. It s taunt due to the size, but not hard. Like a large water balloon under the skin. What could this be and should we seek treatment?
[|AI|]  Hi! Thanks for sharing the case of a painless, skin-colored, taut, soft shin lump with us! Well, this is not so common to have such a big skin grape without any significant history; still I must suspect few possibilities like:1. An allergic scab2. A benign cyst of the skin3. A bursa/ganglion4. Some parasitic cyst5. Abscess6. HemangiomaA simple fine needle biopsy is generally essential to confirm the diagnosis; but not to worry in any case this is benign...Therefore, please see a surgeon/dermatologist for a clinical examination and relevant tests!wishing you good health; regards,
