asked

I have been experiencing a feeling of something coming back up my throat when I swallow, which takes about 10-15 swallows to subside. Additionally, I have pain in the left side of my collar bone that feels bruised, and there is a lump at the end of the muscle area connecting my neck and collar bone. I also have a history of concussion and post-concussion syndrome, and I recently received my second COVID shot. What could be causing these symptoms and what should I do?
