Tingling and electric shock type pains in various places.

I wanted to create a post to see if anyone has had a similar experience. I think it is very unlikely that I could have mets at this point - I had early stage cancer (my tumor was 1.9 cm and a small .1mm branch off from it) , low Oncotype (16), and I am only 1 year past my surgery. My logic side is saying that but I definitely still have trouble with fear. My only treatment now is tamoxifen. I did not have to do chemo or radiation.

I am 31 yrs. old. I have high general anxiety and so I am thinking this could be anxiety-related, however I have never had these kinds of symptoms before the past 3 weeks or so and they showed up rather suddenly and have sustained over 3 weeks, being worse at night. When they first showed up I also felt much more tired and drained than usual, but that has gotten a little better.

Sometimes the pains will wake me up at night. I get electric-shock pains, tingling, and cramping/aching mostly in my right arm and hand. My mastectomy was on my left side. I have constant pain in my right shoulder and between the shoulder blades especially, but feels like regular muscle strain type pain, however it doesn't really go away with stretching, exercise, or rest. I will also get fleeting shock pains in other places like my throat, sometimes feet, and mid-back. Sometimes the pain in my right arm starts in the shoulder and radiates down the arm. I had an ocular migraine a couple weeks ago, but I was told those are common, I just haven't often had them. I also am having very noticeable heart palpitations. I will be going to see a neurologist and I saw a doctor (have normal blood test results) - I think I just wanted to talk about it to see if anyone has experienced anything similar.

These feelings are very unusual to me - I was wondering if anyone else has had anything similar and how were you able to deal with it? Thanks for listening.
