Root canal help needed.?

I got a root canal on my upper pre-molar #4 2 months ago. A couple weeks later I became light headed and got dizzy waves. This stuff has continued since then. The tooth is not sensitive to hot or cold, and not sensitive to bite. I have been back to the endodontist that did it three times, and went to another endodontist for another opinion. x-rays were taken everytime and all looked perfect. The last set of xrays was taken 2 days ago and again were perfect. My question is could my sinus issues be related to this root canal?

Root canal help needed.?
theres a chance that the sinus is allocated near the apex ( tip ) of the root on that tooth, and u have a sinus problem so it feels like it is related to the tooth, there is a small chance that when the dentist was cleaning the tooth ready for root canal that he rinsed some hypochloride out through the apex and that i has got into the sinus, but that very small and u would of hurt almost immediately, i would go see the doctor, maybe u have the start of sinusitis
Reply:You might have an inner ear problem instead of something related to the root canal. Check with your doctor.
Reply:very possible! i had a root canal yrs ago and had problems with my sinuses for months. i don't know if it was actually due to the root canal or the novicane injections but it did clear on its own. by the way, i'll never do it again, i lost the tooth anyway.
Reply:"....light headed and dizzy waves" - could be totally unrelated to the root canal procedure. Have you been eating properly? Have you been drinking enough fluids as well?
Reply:Normally your sinuses can cause tooth pain, not sure if it can the other way around. I would go see your family doctor to see what else it may be. The two may not even be related.
