Dear friend, welcome to HCM.
yes, it could be related.
what was your BP this time?
do you have fever?
headache, vomitting ususlly indicates a high brain pressure , may be from various causes.
it could occur before a brain bleed. so pl. check BP again and seek early help if vomitting, paralysis
, tingling/ numbness
, giddiness ensue.
at least rule out danger signs. it may be due to some simple problem too. you never know.
take care and keep me posted on your progress.
