What Causes Swelling In The Arms?
either erysipelas or local irritation from insect venom
Detailed Answer:
Hello,
your arm has a clearly demarcated area of redness (and supposedly warmth) which indicates inflammation. Insect venom may cause but erysipelas (an infection of the skin) is a big concern here. If it's an infection then antibiotic treatment is required for at least 10 days. Local irritation (something like a small-scale allergic reaction) requires only antihistamines, painkillers and perhaps corticosteroids.
Fever is a distinguishing feature of erysipelas although it may not be always present. If you've got fever then you'd better talk with a doctor for assessment. Otherwise amoxicillin (500mg three times daily is enough for mild cases of erysipelas) and topical administration of anti-inflammatory drugs (like the ones you're using) should help.
So in conclusion, I believe that the treatment you're receiving sounds appropriate although - having not examined you - I can only express my thoughts; not a complete medical opinion that is.
I hope you find my comments helpful!
Kind regards!
I don't have a fever, or any other breathing/heart issues, no other weakness. I have started having a passing tingling in my left hand as I type.
The same bite on my leg has grown to about four inches in diameter. The two bites on my right arm are redden and warm, but do not have the same hardness.
probably the insect venom

You're welcome!
I suppose the bites occurred today? It's normal for the redness to spread during the first hours after the bite. If it occurred earlier (like 2-3 days ago) then this might be a reason for concern.
You talked about your left hand but I've seen your right triceps in the photo. Is your left arm or hand also bitten?
What kind of insect was it? A bee? A wasp? Something else? Did you recognize it?
When the area is swollen it's normal for it to be harder than usual. The hardness can be particularly exaggerated when there's little room for swelling (like when a finger is swollen). The hardness can be less intense even with more swelling in other areas with looser skin.
If the edema continues to grow and there's more pain then it would be better for you to have it checked by your doctor.
Best wishes for a speedy recovery!
Thank you again.

I see...
The black widow usually leaves two marks on the bitten area. So you should be able to recognize it. Besides that so many bites from such a spider would have probably caused much more serious problems.
The brown recluse does not bite unless provoked (like if it was in your shoe and you were trying to put it on) so 6 bites would also be unusual.
Were you bitten in your sleep? An exaggerated response to mosquito bite is also possible if you were scratching it all the time.
I don't have any clue as to what bit you nor can I suggest anything more besides the recommendations on my first answer. If it continues to get worse or if you develop systemic symptoms (like malaise, fever, faintness, etc) then you should visit a doctor again.
Kind Regards!
