What is it? These symptoms indicating?

For full guidance, prescription and follow up take a paid instant consultation. Hope that helps. You can even video consult directly via what sapp on 9999x104x408

If possible get tested immediately...else start your self quarantine and book for a test. Consider Covid positive unless otherwise. Stay indoors, avoid contact, high protein diet, plenty of fluids, fruits. Yes levocetrizine +monteleukast (algicure m) And paracetamol is a good option. However if symptoms persist, I would suggest starting with doxycycline and favipiravir (personal experience of >100 cases of Covid with mild /moderate disease - it's useful  ) Along with your Covid test also get the following done. 1. Blood tests CBC LFT including LDH RFT S. Electrolytes (Na+, K+, Ca+2, Cl-) D-dimer CXR (if possible to attend a facility ) - else if confirmed, at a later date CT might help. 2. quarantine, isolate, get those in contact tested. 3. Sleep Prone and practice deep breathing exercise. 4. Don't panic and start craving for oxygen and remdesivir.  If indicated, you must but if not then resources to be used in national interest.

do step 1,2,3 and get back in touch should it still be hurting.

take care and if needed get in touch for a video consult. best of luck and get well soon.
