Is this sciatic pain?

I am experiencing pain I've felt mildly before but it's getting rather intense. It is a dull pain starting behind my knee and all the way down the back of my leg to my foot. Would this be my sciatic nerve? If so, I'm pretty sure it's likely TMS on the move.

 

Hi, JacketSpud. Knee and leg pain is very common to TMSers. Don't try to call it Sciatic nerve or anything else, just believe the pain is caused by your emotions. The Structured Educational Forum, free on this web site, will help you to discover those emotions.

 

I totally believe it is TMS, I just wondered what nerve is likely affected. Helps with my mindfulness. I've completed the SEP with phenomenal improvements in my original pain but it still recurs and appears to keep throwing up a variety of symptoms that are new and strange to me. I'm now working through unlearn your pain, I'm a week and a half in, so basically I've been going for approx seven weeks. I'm not calander watching, just dos the math quickly in my head.

I'm really pleased with how far I've come, but these other pains frighten the heck out of me - plus my anxiety, which has been dormant for about 18months has come back full pelt, and given I get health anxiety scary pains overwhelm me.
