[|Human|] I found a soft limp on the upper part od my body between the the armpit and shoulder.  Since it was covered in part by my bra strap, I did not notice it until several weeks ago, and I have made an appointment to have it checked.  It is about 2" wide and three inches long, irregular in shape, no pain.  Possible causes?
[|AI|]  Welcome to Chat Doctor .1. The possible causes are lymph nodal enlargement.2. Lymph nodal enlargement is seen in cad if any infection / inflammation / underlying systemic causes / malignancies. 3. There are chances of inflammatory changes localized with the inner were due to constant irritation to the skin, if possible use softer ones for a wile, until it gets healed.4. Visit a doctor and get examined, if necessary doctor may ask for an ultrasound scan. Which will help in identifying the nature of lesion, and extensions. Hope it helps you. Wish you a good health.
