This morning, I suddenly found a small bulge on one side of the clavicle, which grows on the bone. It feels hard like the bone doesn't hurt. It hasn't appeared before
Observing your symptoms, you can consider that it is caused by inflammation or endocrine factors. If it is endocrine, it will cause multiple parts and will not appear alone. Therefore, considering that it may be caused by local inflammatory stimulation factors, you can use mupirocin ointment to treat this part first.
There is no need to worry about this. It generally doesn't matter. It may be caused by the heat on the fire. It may also be caused by the dry and humid clothes or the long pustules on the skin caused by the hard fabric. Usually, you should pay attention to bathing frequently and don't eat the hot stuff.
I suggest you can apply fuxidian acid ointment to this part first for conditioning treatment, and in the process of treatment, you must develop a good living and eating habits, avoid scratching stimulation, and usually avoid using a heavy cosmetics.
