<s>[INST] I received a bullet to my head in the late 80 s entrance wound was on the right side and exited through left ear causing damage to artery. Day before yesterday I started getting large bump on my forehead going from hairline to a fingers width of eyebrow. I have swelling around eye as well as redness to th area described above. Today I m having vision problems with my right eye and I also have bump under the skin by my r ear about the size of my little finger. Both hurts to apply pressure. Would there be any case of bullet fragments moving? [/INST] Hi, thanks for sharing your health concerns with HCM!           As per your description, this is a medical emergency and you should consult ER urgently! There must be some internal bleeding, whatever might be the cause; may be some ruptured aneurysm/hematoma etc. but needs immediate CT scan of brain for assessment and opinion by a neuroradiologist / neurosurgeon.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>
