It was unknown to the reporter that the cream that was prescribed that she was using also had propylene glycol in it. She was using the cream for three months.  She later went to an allergist and did allergy testing all over her back. After the allergy testing she found out she was allergic to propylene glycol. A lot of things have propylene glycol  in it and the allergy started after getting the booster. She had to take propylene glycol out of everything she is using. It took 6 months to find out. She was having burning a lot; it was on her chest and around her eyes. Later realized after testing the creams even the anti-inflammatory cream provided it had propylene glycol in it. She had to go to a special compound pharmacy for them to make a cream without propylene glycol in it to use. Once this was used and the propylene glycol was out of system it went away. The rash was on chest, neck, up through top of breast bone and all around left eye and face.
