Hi sir
if im right then you have eye related and head related problem or possible of blood related issues . since 6th lord aspected by many you have multiple health issues which is also causing you worry .
since 6th lord is own house whatever it may be it wont put you down , you quickly get cured because mars is fast healer , if your 6th lord is saturn then we can say healing takes long time . since it mars it heals soon . ( only physical wounds ! )
i dont wish to give you fake beliefs i say what it is . as it is you are running rahu dasa and that rahu is in moon which is no.1 enemy for rahu . generally dasa results are based on its constellation , since rahu is in moon star and that moon is in 6th along with several other malefics throughout this rahu dasa you will have these troubles it goes on and off . rahu friends bukti will give somewhat relief but again when rahu enemy bukti comes it troubles you again . so always do medical check up engage in devotional service assume you are reaping ur past karma that god has decided to make this life last . so face it with courage , u indeed have that since lagna lord mars is strong
your next jupiter dasa is very good except few bad , but no health problems for sure ......
moon rules mind and blood so take care that well .. year 2022 to 2025 wil give some relief .
saturn or rahu aspecting 6th lord gives lifelong illness ...
