<s>[INST] I have lumps at base of skull, a lump inside my elbow joint and a swollen tongue. When lying flat I have no sensation to urinate but have a sense my bladder is full. When I go to toilet I m left with a weird feeling in bladder, as if it had been stretched and then recovering ...most weird. Have been to doctors but I think they think I m being paranoid ...they said lumps at back of head were folds of skin...but they are hard not soft and I m overweight but not there ... [/INST] Hi, thanks for sharing your health concerns with HCM!   I've gone through your problem of multiple lumps and a swollen tongue and can feel your this embarrassing state of mind and the body ! Well, If I were your treating Doctor for this case of lumps, I would come up with three possibilities, these include: 1.     lymph nodes could be tuberculosis, lymphoma or other chronic inflammatory or malignant conditions2.     The second possibility is of lipoma/neurofibroma-like benign lumps !      3.     The last possibility is cysts/bursa or some malignancy deposits! Therefore, it is possibly a real thing to worry and you must see a surgeon; moreover, I suggest you to go for USG/FNAC test of the lumsp for confirmation and to relieve your concerns!Hope this answers your question. If you have additional questions or follow up questions then please do not hesitate in writing to us. I will be happy to answer your questions. Wishing you good health. </s>
