<human>: I have small lump on trapezius muscle right about the meeting point of clavicle and sternum. I did have an episode in gym where during dumbbell shrugs i severely strained the muscle and had limited mobility in there for about a week. I have no other symptoms. 21 years old. No smoke or drink. The lump is somewhat tender to touch and can roll with my fingers. What could it be?
<bot>: Hi, dairy have gone through your question. I can understand your concern. You may have some tendinitis or soft tissue mass.  You should wait for some time. Furthermore, you should take anti-inflammatory Chat Doctor.  If it doesn't respond to treatment then you should go for examination and if needed go for biopsy. Consult your doctor and take treatment accordingly. Hope I have answered your question, if you have doubt then I will be happy to answer. Thanks for using Chat Doctor. Wish you a very good health.
