Post Covid. Headache & soar throat.

I was tested positive for covid on 23/04 and i completed my isolation and medication (doctor gave azithromycin 500) and got out of isolation on 10th may after having no symptoms for 7-8 days. But on 15th i started feeling pulpatation, some sensations and tightness in the chest and lung area due to which i was unable to sleep. I consulted a doctor and he gave me some medicines and said that i is because the body is recovering. She gave me some medical for 5 days like montair lc, medrol 4mg, Eliquis 5mg, for 5 days and lumia 60k and meganeuron Od for 2 weeks. for two days i was feeling better, then the pulpatation started again. The doctor then asked me to get blood test(CPC, D Dimer, Procal, & CRP) done and EGC & 2D ECHO done. The reports are normal, and after consulation she gave me some medicines like Azithral 500, Lorfast AM, Naxdom 250, Vertin 8, Pan D and Ivabrad 2.5 mg for three days. Now the pulpatation has reduced alot, but i feel sensation in chest, headache & soar throat.
