Night sweats after COVID

Hello everyone,
A few weeks ago I got COVID for the first time (as far as I know). It was mild and I have fully recovered.

However, I am recently experiencing some dry cough and night sweats (for the last 4-5 days). I have never had those before (only cough during Covid), and they both appeared at the same time.

I have had no fever except for one of the first night where I felt dizzy and tired and also got a very mild fever for a few hours. That night is when it started, i had very intense night sweats and now seems like they're getting less and less.

I am wondering if this could be a post COVID symptoms. I have some blood exams scheduled because I am terrified about other possible diseases like Lymphoma. Has anyone had similar symptoms within a month of COVID exposure?

Thank you in advance
