 [ Symptoms ] how long after being treated for chlamydia is it safe to have sex i did the one time dose of 4 250mg azithromycin tabs [ Disease ] i am sorry to hear of your husband is health problems it is difficult when they begin to stack up like that several things could cause your husband is ears to turn purple when he lies down the most likely thing is a lack of oxygen due to congestive heart failure you might see if propping up his head and back on extra pillows makes the purple ears go away this is something you should talk to your husband is doctor about because it started happening recently your husband is doctor will want to know about it i suggest you call for an appointment hope this helps take care
