<s>[INST] Hello, i was scracthing my left arm and i notcied a small bump that appeared to be on the inside of my left arm to the right and slightly lower then the crease in my arm. Is not noticable by sight. I feel one on my rifght arm aswell. I bekive they re lymph nodes. But im not sure [/INST] Hi, The location you mention is more likely to have lipomas or lumps with fat cells. This is a very common condition, and they can appear at almost any place but are harmless and do not trouble. No treatment is required for them usually. But, if you feel they are hard or firm, or they seem to be lymph node swellings then you should get an appointment with your GP. Let him examine you and advice whether any further investigation is required. Take care and do let us know if we can help you with any other queries. Chat Doctor.  </s>
