[|Human|] Hi. I hae a blood clot and am currently taking Arixtra injections. After one of the abdominal injections I started to bruise, fairly normal. However this bruise has spread and is now roughly 6 inches by 3 inches. I also noticed that there is now a noticible lump under the bruise. The lump is much smaller then the bruise. Should I be worried?
[|AI|]  Hi, From history it seems that due to Arista which is anticoagulant medicine used to prevent clots in the blood there might be having bleeding tendency might cause hematoma over the part giving this problem. You might require estimation of Prothrombin time (INR) and accordingly the dose of anticoagulants to be adjusted. Consult your treating doctor and discuss this.Meanwhile, apply ice pack 2-3 times a day for few days. Ok and take care.
