I have a red bumpy rash that started on right front shoulder and has continued to spread whole chest, shoulders, back, and now starting to spread down my arms and down my back. Have had a horrible cold for weeks. Cold better but this is worrisome. Almost looks like measles or chicken pox. I take Lomtrigine and when filled on the 27th was from a different company. Trying to figure out if allergic reaction due to new mfg of Lomotrigine pill. A lot of other symptoms but just overview to get your opinion before losing sleep tonight . Skin feels tight and swollen. Glands in neck and under arms are swelled.
