If you handle cattle... Or any four legged beasties for that matter you will more than likely, sooner or later, be confronted with an abscess... I would say that they are painful for the animal in question... And IMHO... Not too tough to address....
I would first like to say that any swelling around the navel area could more than likely be a "Belly Rupture"... i. e.... umbilical hernia.....

We can discuss "Belly Ruptures" at length too if anyone is curious about them......
That said.. Abscesses are commonly caused by infection of an injection site.... Or infection caused by another type of puncture wound...... The resulting infection can swell rather noticeably..... If you do see a large lump appear on a hip, thigh, neck, shoulder or jaw it might just be no more than an abscess.... If there is swelling on the jaw or neck there are other possibilities to consider too... i. e...
Actinomycosis or Lumpy jaw....

Actinobacillosis or Wooden tongue......

Necrotic Laryngitis or Calf diphtheria...

If the calf, (Or other critter).. Appears to be of normal overall thrift, appetite and temperature (normal range for cattle is...101 1/2 - 103 degrees)... You might just be dealing with an abscess...
I would invest in some latex gloves (Nitrile... if you are allergic to latex) and palpate the lump regularly to ascertain if there are any changes.... If it continues to swell.. Is not bony to the touch..... Yields under pressure... And the animal flinches from the added pressure on the site..... You may wish to attempt to drain it.... Procure a syringe of at least 20cc in size.... Used and cleaned will do as you are not going to make an injection per sey..... Procure a new unused hypodermic needle of at minimum 18 gage or larger... 10 ga.... If you can get one..... Inject the needle as gently as possible and as shallow as possible (Only puncturing all layers of skin.. If it is some type of hernia on the belly region, you don't want to puncture a gut)... Gently pull the plunger as if you are attempting to fill the syringe.... Because you are...... Draw out some fluid for examination..... If the fluid proves to be only fresh blood.... IMHO... you are dealing with something other than a common abscess..... If it is either Pus, or bloody pus (Degraded blood will appear brownish)... Then you are probably dealing with an abscess
You might want to get a scalpel (Or sharp knife... Or one of those nifty box blade jack-knives)... And attempt to drain it...
If you decide to give drainage a go... Shave the affected area with some electric hair clippers (Wal-Mart cheepies will work)... Use a disposable razor to shave the affected area (Probably overkill)... Get some Betadine and scrub the shaved area..... With a sterile instrument.... Puncture the center of the swelling, being careful not to make too much of a puncture..... If it is full of pus... Or bloody pus... It may be under some internal pressure and will give you a nasty bath... So use caution... Also if you penetrate all of the layers of skin and fail to draw pus you will not want a gaping wound.....
If indeed there is an issue of pus... Open the incision a bit... If necessary... And apply some gentle pressure to the swollen area to facilitate drainage.... I would than make a mixture of bottled (Boiled) distilled water and Betadine and infuse the abscess with the solution to flush out any residual pus.. Using a syringe as the delivery medium.... Saturate a sterile gauze bandage with Betadine and insert into the incision... This will keep the incision open....
Continue to irrigate the abscess pocket daily and change the gauze until.....
(You might wish to procure some hemostats to assist in the removal of the gauze.... Tweezers or needle-nose pliers in a pinch... (Get it?... Pliers... Pinch?.... Oh well.. You would probably had to have been there....
).....You see a reduction in the swelling..... I am of the opinion that Neosporin (Wal-Mart, triple antibiotic ointment) is a wonder drug for cuts and abrasions..... Get an adhesive bandage that is large enough to cover the incision and dope it up real good with the Neosporin... You can make one out of medical adhesive tape and gauze..... Apply that to the incision... remove it in two to three days... Observe the healing... And change the dressing..... Repeat as needed until healed...
Of course this is the advice of a non-professional Net-Vet... So take it for what it's worth......

It might also be advisable to invest in a few surgical needles and thread..... Just in case you have to close the FRESH wound surgically.. Old wounds don't sew up so good..... Also.... Ordinary sewing needle and thread will work in a pinch... just sterilize them by soaking in rubbing alcohol before use... remove the stitches after a couple of weeks.....
