Thanks for the valuable input.
I think if there is persistant bleeding from the wound, you should get this examined by the doctor in ER.
A tourniquet is fine to control profuse bleeding for a short duration, but if applied for a long time, this can result in cessation of blood supply to the area beyond it, which inturn can cause tissue injury and death (necrosis).
The best way to control the bleeding from such kind of wound is to apply a pressure dressing, after cleaning the wound and applying antiseptic over it to prevent any possible infection (which can develop in it).
Plavix and Aspirin can make the bleeding worse, but if adequately controlled by pressure dressing, you can continue with these.
If the dressing also fails to control the bleeding, other measures like stitching the wound, ligation of the bleeder etc can be employed as well.
So right now going to ER for an urgent help seems to be the most appropriate plan.
You need not to panic as this is a common and treatable problem, and will settle down with appropriate treatment.
I hope this clarifies and answers your question.
Kindest Regards and Good luck.
