Hi. About a month ago I got a minor concussion. Hit heads with my cousin tubing. Didnt get knocked out but got pretty tired after and felt out of it. Minor headaches for a lil while but was feeling alot better when about 3 weeks after the concussion I hit my head on a glass table standing up from sitting on the ground. Since then I have felt irritable, anxious, out of it, and have had trouble putting my thoughts into words, and became pretty forgetful. I didnt get knocked out or anything, and at first didnt think it was that bad. Its been a week or two since then n while I feel a bit better everyday I am still not feeling myself at all. Could these 2 minor hits to the head cause any permanent damage?
