Will my blood go back to normal after long term heavy use of aspirin. i'm worried about blood clots forming but i believe the aspirin is hurting me ?

Yes: Aspirin impairs the ability of platelets (clotting cells) to bunch together and form clots. The effect aspirin has on each platelet is permanent, but a platelet only lasts for about 10 days before it dies and is replaced by a new one. After stopping aspirin therapy, any affected platelets will be gone within a month at most, more likely 2-3 weeks, and the replacements should be normal.
