Hi I have multiple tiny red spots like the size of the tip of a sewing needle on my arms. I do not know if they appear anywhere else since I can not look that close to other parts of my body. I am just concerned as to whether it is caused by seasonal allergies which I have or if it can be caused by any of the medications I could be on (Adderall, Prozac and Loestrin). I was at one time diagnosed with hypothyroidism, then was told I did not have it so I am not to sure if I still suffer from the above mentioned diagnosis. I also know my mother has had her spleen removed for some immune reasons I am not sure of. I have read about cherry angiomas and petachiae.
