When I want to express honestly about your sinus issue, let me come out and you act upon it or not is your own choice.
You have had or may go for another series of blood work etc. Your sinus issue will not be solved permanently by any modern approach.
Association of
abdominal pain has no direct link with sinus as explained in modern medical approach.
The sincere advise for you is to adopt safe, economic, side effect less Ayurveda approach for the issue of sinus. Chances of 80-90% or more cure are 99%.. The medicine may not be palatable, may be bitter or pungent but that's the beauty of pure herbal, non synthetic medicine.
Chitak
Haritaki and Agastya Haritaki are unparalleled medicines to be licked and Shadbindu oil for nasal drops will do the wonders in about 16- 24 weeks. Effect will be visible in 15 days.
In Ayurveda, abdomen is seat of Kapha humor and
sinusitis is complication of kapha vitiation. So they have direct link. Both will be cured with these simple things. Do not make haste to get results in a day or two which were not there even with fastest modern medicines.
Procedure to take these medicines empty stomach, no food for two hrs, warm water vehicle to use these, nasal oil instillation in the very early morning hrs etc will be told by your local Ayurveda doctor as per his experience. Avoiding
cold drinks etc and heavy food is also important during treatment.
My experience of three decades will change your life.
Hope you get the hint. I will be happy to help a sportsperson.
