Question: I'm 36, 152 lb. female, and I have a VERY itchy skin rash on arms, legs, and torso. I am nauseous and running a low grade temp. I am nursing my 18 month old. I take, and have taken for a long time, 100mcg lovothyroxine, 500 metformin (pcos), prenatal vitamin, calcium, and low dose asprin (prothrombin factor 2), and claritin (for seasonal allergies). My only known allergy is penicillin. I am a stay-at-home mom and not in contact with tons of people, and otherwise healthy. My husband has not been ill. My daughter had brief allergies in beginning of October and used an inhaler for two weeks, but otherwise healthy.

I have seen the doctor several times in the past two weeks with a different diagnosis each time.

10/24 concern: rash on undersides of breasts
Diagnosis: thrush
Treatment: Nystatin cream (nursing daughter prescribed oral Nystatin by phone consultation.)

10/31 body rash develops on arms and legs with low grade fever
Diagnosis: labeled pityriasis rocea NOT thrush (based on visual observation)
Treatment: stop Nystatin cream

11/2 body rash spreads to torso, worsens. fever persists. vomiting develops.
Diagnosis: Parovirus rash, NOT piyriasis rocea. (based on blood test negative for bacterial / white blood cell count AND no Christmas tree pattern)
Treatment: Allegra AM (in lieu of Claritin)/ 2 dose of Benedryl PM / hydrocortisone cream for itching

I am tired, sick, itchy, and struggling to keep a milk supply. I am losing faith in my doctor, and I am not improving! I had a lightbulb moment this evening. I started taking (at urging of doctor) a probiotic when thrush (that wasn't thrush) was diagnosed. I have been drinking Good Belly Probiotic Juice Drink (lactobacillus plantarum 299v) daily. I quit taking it a few days ago when diagnosis changed yet again. This is the only dietary change I have had recently. Can I be allergic to probiotics? Can it cause stated symptoms? If so, does it require an additional visit to doctor for treatment or will it resolve on its own? What is a timeline for health improvement? Is this a concern for my nursing daughter? If I'm totally off base, does the latest diagnosis sound appropriate?
