[|Human|] Hello, I have very week veins as I had a lot of iv meds now after three weeks of the canulas being out of my hand and arm my hand and wrist is very sore and lumpy with numbness in my right hand near the site of the canula. My left arm has two lumps from another canula site which is turning black and the lump is becoming bigger and sorer. Should I see my GP or will it go away I think its thrombosis of the vein in my left arm . Thank you
[|AI|]  Hi. Welcome to Chat Doctor . I have gone through your query and can understand your concerns. As per your complaint large painful lump at the site of cannula insertion can be due to a few reasons like Hematoma formation, formation of a blood clot in the vein at the site of Cannula insertion or can also be due to localized infection leading to abscess formation. I would suggest you to consult your treating physician and get evaluated and in case of hematoma formation alternate warm and cool compresses will relieve, for pain you can take anti-inflammatory painkiller like Ibuprofen, but in case of infection oral and injectable antibiotics are needed for resolution of infection. Hope this information helps. Thanks and regards. Chat Doctor.
