When you get your report back from the Dr. and it is normal, chalk it up to adrenaline surges. It's usually something you ate that you shouldn't have, or it could be gastric problems which is normal for withdrawal. I've just had 5 straight days of surges, stomach pain, breathlessness, heart palps. It's to the point that I don't worry too much about them anymore. It's nerve racking but I just try to ride them out.
It's when I get a new symptom that I post here like you, to see if others have had the same sxs.I have the other problem that you don't have .... constipation, and I have a problem no matter what I take for it.
You're still early out from your jumping point, so it's hard to say when it will subside.
I pray that you will heal quickly.
