Any injury to the arm?
Do you have fever?
Do you suffer from any medical condition?
Any prominent or inflamed blood vessel seen?
How did this start?
Does arm show bluish discoloration?
Is pain associated with the swelling?
From the details provide I think possibility of blood vessels thrombosis needs to be ruled our in your case.A clinical evaluation and color Doppler study needs to be undertaken.
Other less likely possibility is of Cellulitis but it would be associated with fever.
Yes, please see doctor sooner.
Ok then even possibility of cellulitis might need equal consideration.The doctor can make out the difference after clinical evaluation.
Please ask if there are doubts.
If satisfied please ACCEPT my answers.Thank you.Take care.
First diagnosis has to be confirmed.You can take oral analgesics for pain and to reduce inflammation.
