I am a 26yo F. On July 8th, 2021, I notice this hard, painless lump on the left side of my neck. I attached a picture of it. It is not mobile at all and has not gone down with daily stretches, ice packs in the mornings, and heat pads in the evenings. I had some pretty bad neck pain in the back of my neck to shoulder blades around the time I discovered the lump but that has since cleared up. The only other thing I've noticed is fatigue.
Went to my primary care doc, she basically shrugged her shoulders and said it could possibly be due to muscle injury (I cannot recall one) but still referred me to ENT. ENT doc basically did the same thing but said to do an ultrasound next month just in case. Bloodwork including CBC and Thyroid panel came back normal. Has anyone ever seen anything like this? I have not been able to find photos of patients with similar neck lumps. Hopefully it's just muscular but wouldn't an injury be painful?
