[|Human|] Wow, cool... Um, I have a lump on the back of my lower neck (almost shoulder).  No redness or swelling, just pain. No external signs (no puss, skin breakage).  The skin rolls over it easily, but it feel attached to the muscle. I woke up with it suddenly yesterday, and it has not changed. It is quite hard and unmoveable. Should I be worried?
[|AI|]  Hello, Thanks for writing to swell, without a clinical evaluation it would be difficult to determine the cause of the lump. Possibilities that may need to be considered include lipomas, cysts, growths from underlying connective tissue etc. I would suggest getting this evaluated by your doctor for an accurate diagnosis and appropriate management. You may get the X-ray of the area affected and FNAC (fine needle aspiration cytology) of lump under his/her guidance. I do hope that you have found something helpful, and I will be glad to answer any further query.
