Hello PrimeTimer,
I am sorry for you both about this distressing experience. Could your husband ask his GP about his usual pain-killers for the time being?
In case your husband suffers from high BP please let him be be careful about the dosage of "Ibuproven", as a very high dosage could "thinnen his blood" and could lead to further issues.
Please take great care and good-luck wishes from Kristina.
