You can get the following tests done:
1.
CRP
2. D-Dimer
3. Serum
Ferritin Level
4. IL6
5. CBC
If the situation doesnt improve, get these test reports done on priority and consult a doctor. Weakness in covid takes time so you shouldn't get too worried, but at the same time it is important that we properly observe the patient and keep a healthy course of treatment for steady recovery.
If you notice any worsening symptoms, dont wait for the reports to come and consult a doctor. And remember worrying wont help, acting on the situation will.
