I am a 55 year old male. I am suffering from inguinal lymphadenopathy. 2 years ago I have this on right side and now on left side. There is a square shallow knot present on the right side now. I have stiffness and rigidity especially in the left arm and occasional limited movements. Also I have discomfort in my legs and inguinal region. On ultrasound it was observed lipomatosis of inguinal lymphs. I have painful point in inguinal region, only if I press. I have noticeable weakness, but no weight loss. Occasionally I feel very low energy and could not maintain erection. I feel numbness in the shoulder or finger when wake from sleep. I have low sedimentation rate. There is no abnormal blood and urine finding. I had blood test and it is negative for all infectious diseases such as Lyme, cat scratch, AIDS, etc. Please help with some suggestion. Thank you.
