I'm 35 recently had shoulder surgery. devopled a blood clott. will i be more septic to them everytime a have surgery ?

Blood clot: I assume the clot was in the legs. You must be at high risk (like being on contraceptives etc...). Next surgery have compression stockings, or pneumatic leg compressors used. While these decrease the possibility its never 100%. Just because you had clots once does not mean that it will happen everytime.

Septic?: Or susceptible? Perhaps if it was leg and not arm phlebitis you are more at risk.
