<s>[INST] I have a lump under the skin on my chin. I noticed that it got bigger. Then there was another small lump next to it, now I found more small lumps on the right side of my face at the chin line every day they seem to get bigger. I don t know what to do. [/INST] these are nothing but benign sebaceous cysts. they arise from minor trauma like shaving or itching.not to worry much but just take caution not to infect them.all the best! </s>
