Additional Information: Stated she got her second booster for the Pfizer covid vaccine yesterday (16Jun2022) administered on right upper arm and just finished her workday and looked down and her arms have gotten all splotchy and it was not really like a rash but for a very pale skinned person she has little red splotches all up and down her arms and has it on her thighs down over her knees and the skin was all red with splotches and she was calling to know if she should freak out about this or it will go away the same as the redness around the site after the vaccines. Stated the red splotches just were noticed right before she started looking for a phone number to call. Stated for the red spotches she has not started anything or taken anything for this. Stated she also has ringworm that began and she started taking an antifungal cream last Friday and that was when she noticed it and had the HCP through telehealth when she was asking about her allergies she gave the caller a topical treatment to use for that but only on her legs and not on her arms and the ringworm began on 10Jun2022; states it is distressing that she cannot find the antifungal cream and needs to find it before the end of the day. Patient stated the topical antifungal cream is Ketoconazole to apply topically daily to affected areas for two weeks and to keep it on as often as possible; stated the Ketoconazole has lot 637121, expiry date Jan2024 and has GTIN and SN number and also has NDC 00093-3219-92; states the Ketoconazole was to be put on the two spots of ringworm she has and was still getting ringworm and is taking Ketoconazole still and this morning she had a second location where it was starting and started using the antifungal cream for that. Astelin started a week ago states she had really bad outbreak of allergic seasonal allergies but it was not infection- 1 percent nasal solution two sprays twice per day and reduced this week to one spray twice a day. Comments: Sjogrens disease and symptoms started approximately 20 years ago; states she does not know if Pfizer records any other kind of health issues but the Sjogrens and the hypoactive thyroid are her two autoimmune diseases and sometimes other health issues play into a reaction.
