<s>[INST] Hi I gave blood for the first time last Saturday and now I m getting theses little red bumps all over the area they took the blood from. They re very itchy and I would like to know how to calm them down or even get ride of them I would also like to know how I got them. [/INST] Hi, Thanks for posting in Chat Doctor. Blood donation is quite safe, and you have done a good thing by giving blood. Little red bumps appearing at or around puncture site and itching sensation is just an allergic reaction due to the use of adhesive plaster material. You can take Tablet. Levocetrizine 10 mg once a day for 3 days. Your symptoms should gradually reduce and disappear in a day or two. All the best. </s>
