<s>[INST] I have an undiagnosed inflammatory disease = 8 months now My spine burns up to 5 or 6 days at a time, and I become too exhausted to know what I am doing. Now, I have a small, hard lump on my arm under the elbow = the burning of my back and spine just consumes almost every day of the week. I cannot see a rheumatologist for a month and a half. [/INST] Hi and welcome to HCm. Thanks for the query. Well you should do ultrasound and xray to verify what kind of lesion is this lump. it ca be related to your primary disease but also it can be something else. Most commonly we see ganglion cysts,bursitis or bone exsostosis. Wish you good health. Regards </s>
