Any doctor please help joint pain , sinus and sleep problem

i am 35 male , height 5.5 , weight 72 .
My problem is -
1. since past 8 years I have sleep problems. Around 70 % of times I feel as if I have not slept as in the morning when I wake up there is pain on back side of head above neck. This pain continues h the entire day and becomes better in evening / night. ( I took allopathy medicines like clonazepam, paroxetine hydrochloride but now I have left all that )

2. Since last 2 years I have also sinus problem where I get frequent sneezing and watery discharge in the morning which becomes fine after one – two hours but left side of nose remains somewhat blocked so I breathe mainly from right nose. I took allopathy medicine, nasal spray antihistamine for some time & then I left as everyone says u should not continue allopathy for long )

3 . Four months back one doctor gave me allopathy antinbiotic chloroquine for cold cough fever. Since then I have intense pain in my joints . Doctor says its normal but all joints – knee, hip, elbow are paining. Knee has swelled. Also I have to burp a lot and also flatulence relieve me as I feel excess air/gas inside .

Doctors say its autoimmune disorder . But I don’t know if all three prlems mentioned above are related to each other or they are different . But different doctors are giving different theories So I am all confused and also I want to avoid allopathy. So please suggest homeopathy medicine.
