Post covid check-up. Completely?

I was affected by covid positive on 3.5.21  which was mild and undergkne homequarantine and taken rest till 31.5.21. My Doctor told there is no need to have covid test again. So I reported for duty from 1.6.21. I am having backache and weakness and lost weight around 5-6 kgs. Though I am  recovering slowly I have in my mind that, am I recovered completely ? I feel that I should have a medical check/test for pneumonia if exists .  Becz some time, not regularly, I spitted greenish  kapha .I had already taken 1st dose of covishield on 10.4.21, but got affected after 20 days of vaccination. 2nd dose  should be able to take only  after 3 months from recovering from covid. I'm taking steam inhilation once in the night and salt water gorgle in the morning. I'm not having any comorbidity and not taking any medication  post covid period. Please guide me doctor.
