Hi, thanks for sharing your health concerns with HCM!
Yes, you are correct; this could well be a
hematoma, delayed hematoma following
injury Anyways, If I were your treating Doctor for this case of painful back of head lump, I would come up with three possibilities, these include:
1. a hematoma
2. The second possibility is of an enlarged
lymph node
3. The last possibility is of infected sebaceous
cyst or some other cysts like parasitic cyst!
I suggest you to go for an FNAC and
ultrasound 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.
