It may be possible the pain isn't related to the tooth then. The pulse pain should have went away fairly quickly if it was due to a bad tooth. You should go back and get a follow up.
It's been 11 weeks and im still having the pulse problems and weakness bad.My gum where the infected tooth was has still not fully healed.
How difficult was the extraction? It may take some time to completely heal but the pulse pain should be getting better at least. I'm assuming once the tooth was removed, the majority of pain/symptoms were gone?
The Dentists put me on antibiotics and 3 days later he pulled the tooth.
So you had the abscess starting 4 months ago and 2 months ago you got treatment. What type of treatment was it?
I would always recommend contacting your dentist to find out more.
