[|Human|] About 4 days ago, I noticed a pea shaped lump on my forearm between my wrist and elbow. It is painless and under the skin. What could it be? I have been taking medication for coughing, sneezing, and runny nose since before Thanksgiving. Also, I received a steroid shot.
[|AI|]  Hi.based from your description, it could be a cystic formation (tedious or ganglion cyst), lipoma (fatty deposit) or a fibrous (fibrous tissue formation). It is best if you consult with a doctor, preferably a general surgeon, for physical examination and clinical evaluation, especially if the lesion is persistent, increasing in size and is bothering you. Other lesion types must also be ruled-out. Definitive management is excision biopsy of the lesion. Hope this helps. Good day!!~ Chat Doctor.
