Hi Sandeep Rana,
You need to visit a good dentist
ASAP. An appropriate course of good antibiotics, deep sub-gingival cleaning & filling all the decays will solve most of your problems.
Why have you neglected the bleeding for 2yrs?? Poor dental hygiene lads topoor general body health.
GARGLE every 4th hourly to reduce infection/inflammation till you get to a dentist
Thanks & take care
