Thanks for writing your query
After going through your suffering, it does not looks to be serious brain injury
as you are fully aware of how it happened and minimal loss of consciousness
.So,my advise would be take trypsin/bromelain comination to reduce swelling and thrmbophob ointment for local application.You will be alright in 2-3 weeks time .
Hope this information suffices and I shall be glad to answer any further query.
Take care and wish you good health
