Hi, thanks for sharing your health concerns with HCM!
I've gone through your problem of left hip lump and can feel this 'hard/ spongy and can be moved almost it is rather round sort of like a meatball' lump!
Well, If I were your treating Doctor for this case of hip lump, I would come up with three possibilities, these include:
1. a bursa-like inflammatory / degenerative pathology like
ganglion cyst
2. The second possibility is of lipoma/neurofibroma-like benign lump !
3. The last possibility is a large
lymph node could be due to some local inflammation!
Therefore, it is possibly not a thing to worry but I suggest you to go for USG/FNAC test of the lump 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.
