[|Human|] My granddaughter injects herself each day with Clexane a blood thinking drug. Two days ago she had trouble with the needle, it didn t feel normal as she pushed in the needle, but she continued with the insertion of the Needle,12 about a few hours she developed a lump and it is the same two days later,with some pain, it is redissh blue in colour, can you advise, thank you
[|AI|]  Hi. Thanks for the query. As per your complaint a painful lump which is reddish blue in color suggests that there is perforation of the blood vessel while insertion of the needle leading to spillage of blood into the adjacent soft tissues leading to formation of a HEMATOMA. Pain can occur in case if the nerve fibers are also pricked during needle insertion leading injury of nerve fibers and eventually causing pain. The swelling and discoloration will slowly resolve as the hematoma will slowly get disintegrated, and the nerve healing will take place. You can apply alternate hot and cold packs over the lump for faster disintegration of hematoma and relief. In case of pain over the counter painkiller like Ibuprofen can help. Hope this helps. Thanks and regards.
