Hi, there. I was in here and read back to your post. How are you doing? Were you able to hone in to the issue with the leg numbing? I still get them from time-to-time, however, not with headaches. I hope you are doing much better since your last post.
Thanks so much for messaging back. I actually got the physical report and images from my MRI. The report mentions a Tarlov Cyst at the termination of the central canal. So I was confused and did a little research on it. Apparently it can cause all of the symptoms I am having including my headaches. So I am going to have my neurologist and neurosurgeon look into it further.
About a year ago, I also started experiencing the leg numbing. It would switch from one leg to the other at different intervals in time. Then, it stops for a period of time and starts back up. One thing I do notice is that if I stand for a while, the left leg/thigh starts numbing. I read online a while back and I think it had to do with a nerve in our genitalia area. Unfortunately, I didn't keep researching because of the infrequency it happened. I hope you are able to figure out what is your medical issue and that you find relief from the migraines.
Hopefully, someone here may have a suggestion or answer for you. Good luck!
