Hi again! (I also posted to your first thread just a second ago:)
As long as you have had a medical screening recently, and you are considered to be healthy by your docotors...then I can guess that your symptoms are coming from worrying about
them. Health anxiety is pretty common, and the subject of many posts here in our forum!
Anxiety can cause a wide range of physical symptoms. It is hard to accept this sometimes, as it feels like there is something seriously wrong with our bodies...but the mind/body connection strong, so it makes sense that when something is off in our thinking, our physical self will feel the effects.
If you would like to check out this link, it will give you a comprehensive list of things that anxiety can cause us to experience:

Hopefully this will give you some reassurance.
