Hello. Today I had come to station to pick someone. I entered the train and while getting down I bumped into shutter which was lowered down and I could not spot it. I did not lose consciousness but After this I am having some symptoms. I can feel a small raised bump near the area and some minor headache. My face also feels hot .. No problem in alertness, memory or major symptom. Please suggest me is there any need for further intervention? Can I put some cold or hot compress on that area?
