Hi, thanks for asking from HCM.
I can understand your concern. It is good that you are conscious and oriented. The leak from knot could be inflammatory serous fluid/serum or blood discharge. If it is thick, sticky and transparent, it is serum and if it is red, it is blood. Kindly get it examined. You need dressing over it. If there will be open wound, you might need stitches.
The blood in nose could be due to
injury to nose. As you mentioned, there was small amount, it was most probably erosions. You can wait. If there is no frank blood/only
blood clots with no active bleeding, it will heal on its own. If there is profuse bleeding/blood with watery discharge, consult ER. You might need a NCCT head to rule out any skull base damage or CSF leak. Avoid blowing and picking of nose.
The headache will be there for few days. You can apply icepacks at injury site. Also take painkiller like acetaminophen/
diclofenac after proper prescription. Avoid pressure at pain site. If headache worsens despite taking painkillers/ headache with projectile
vomiting, you must consult ER.
In such case, NCCT head is advisable to rule out
fracture or bleed.
Usual treatment is conservative. Surgery is needed only if large bleed with mass effect.
Hope it will help you. If any doubts, do let me know.
Thanks. Take care.
