Apparently this is very common. Matia tells me it's my lymph system not working properly. She says it will improve. I have had it for a while now. I don't know if its' the same for you but if you put chest pain or tight chest in the search you should get more posts on it. I know I had responses from others. I hope it passes for you.
Try not to worrie about it and just tell Matia.
