<s>[INST] I have a very large, and very hard hematoma on the outside of my thigh, that is quite noticeable even through pants, especially leggings. I ve had it for five years, and my doctor said that it is harmless, and I ll probably have it for the rest of my life. Sometimes it gets real sore, but most of the time it s just a ugly nuisance. Is there anyway I can shrink it of get rid of it, without surgery? If I decide to do surgery, how is that done, and is there any downtime? Also, can a doctor say that it is a necessary procedure, instead of elective or cosmetic? [/INST] Hello and thanks for your question.It's my first priority to help you.You can try topical heparin sodium ointment on affected area to heal it.Hope this helps. </s>
