This sounds very worrisome. Two weeks is way too long for your pain. I would strongly suggest a visit to emergency (since your doctor does not know about ostomies) despite the fact that medical staff are busy. You are important too. Perhaps, if admitted into emergency, they will give you a test as a precaution. I am not religious so praying might help; I am not sure.
In Aberta if we suspect Covid-19 symptoms we are encouraged to do an online self-assessment tool that will direct us to the next step in the wellness process. https://myhealth.alberta.ca/journey/covid-19/Pages/COVID-Self-Assessment.aspx. Does your state have a process like this?
Something does not make sense here. I have been listening, now and then, to your prez's daily speeches. He continues to say that everyone can get a test and that the US has the best testing process in the world. I am doing the math here and according to a per capita calculation (2 million out of 350 million) is less than the population of Calgary. That's not something to keep telling the good citizens of America especially when I hear stores such as yours - and others as I have family living in the states as well.
Also, I am not sure how many ostomates have actually been tested for the virus.
Please seek medical advice to rule out anything serious. I would also use the fact that you have an ostomy (a possible blockage) to get some quick medical attention. We have a Health Link Call Center and if you have only one working kidney or heart problems, or an ostomy, you are one step closer in getting help BEFORE someone else who may have a lesser emergency. This has served me well in the past. Actually - I would rather give birth than deal with another blockage again.
I will be thinking of you.
