as someone with multiple medical people in the family, this is just wild IMO.... if after 14 days of Doxy didnt work and they havnt cultured it yet, just what the heck?! Id possibly mention that to your dr when you go back on Thursday like "why havnt we cultured this to see which AB we should be using if these havnt worked?"
Wishing you the best man, medical stuff can get messy
I will definitely ask and let you guys know. at this point I have no idea either.^ 100 % demand it otherwise get a new doctor
