hit forehead on car door. goose egg and slight headache should I go to emergency room

I have what I thought was a bruise falring up a bit on my right chin / jaw line. I could feel the bump but could not remember being hit to cause such a decent size lump. My children often kick and hit me in the face in play. But to get this size lump would have been memorable unless at 39 my body now can't handle even a gentle bump. But it seems to now be getting slightly worse and is begining to feel numb and slightly itchy. I have a very mild middle bottom tooth infection. I thought if my gland was up it would be a lower / under my chin swelling which it is not under the chin but on and if anything above. I am visably looking like fred flintstone actor's chin on one side / elephant man slightly.

So i got 5 teeth pulled as well as 2 root canals andthey put a temp bridge im on clyndamiacin for4 days but now its hard to breathe and my tongue is covered in thick yellow stuff please respond so i know if i should go to emergency room

hi, I am 26 year old male.My heart pulse rate is 100 bpm at rest, blood pressure range from 120-136/80-90, when high blood pressure I have pain behind eye and headache. I also feel chest tightness sometime. when I walk or do physical activity I can feel slight breath. From recent blood work my chelostorel is 245. what could be the problem?

I am facing breathing difficulty from last 3 days. I am allergic to dust. Few days ago, while sleeping I wasn't taking a breath, my room-mate awaken me. Also have difficulty in concentration, tonsil pain and small amount of headache with appetite lowered than usual.
