[|Human|] I have been losing a lot of weight after finding out I was hypothyroid and going on levothyroxine. I recently found a hard lump on my collarbone down by my shoulder. I have had discomfort that moves for. My neck and into my arm for what may be are and I am still very tired. I don t know how long the lump has been there but I noticed it a week ago and it hasn t. Changed any. It moves but not by much and seemingly one direction only. It is uncomfortable messing we it. I am 29 years old. I do have an inhaler to see if it helps with my breathing thinking I may have exercise induced asthma. I feel like I will hit a wall and not have muscle tone or catch my breath and must stop a few minutes to rest and then I can restart.
[|AI|]  Hi, dairy have gone through your question. I can understand your concern. You may have cervical lymph node enlargement or soft tissue tumor. Lymph node enlargement may be due to reactive hyperplasia, tuberculosis or lymphoma. Soft tissue tumor may be lipoma or neurofibroma or something else. You should go for fine needle aspiration cytology of lump. It will give you exact diagnosis. Then you should 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.
