Bug Bite or Thrombosis?

Question

Ok, Well here are the symptoms of my left foot; Swelling, Aching, Yellow skin around right side of foot, red in middle of foot, purple down left side of foot from bottom and half way towards the middle now spread to Ankles. Its not itchy, Its burning sensation and aches. Its swelled so badly that I push my skin then it indents like retaining water, although it doesn't undent for like a few seconds like 30. Its got dry skin over it now, I felt something bite me 2days ago and now this has happened. It began with a bruise circle on the right side of my foot, slightly purple then it spreaded to above my toes now the entire left side is purple. I cant put any weight on it because it kills, I've took inflamtry pills and anti-biotics for past 2days and put a ice-pack on it per 60minutes through the day. Its began to leave stretchmarks because its swelled up so badly, The skins rock hard basically. I had the same thing but it was opposite, More of a hot and itchy sensation with red swelling on my right foot and I had Thrombosis scan although it came back clear on my left leg. Apparently it was a red-ant bite, I just had a bad reaction. So I think the thing that bit me was a spider or dustmite Can this be possible to a bad reaction? I looked it up and apparently its similar to a venemous bite from a insect. Im going to the hospital in about 15hours, I dont wana waste my time up there again. I spent near on 5hours up there last time. I sit down alot due to my work I do currently is computer based, Such as website design etc. Anyone able to give me a decent diagnosis or websites etc will be much appriciated. Thanks in advance. If you need further details ask & I'll post them in the detail bit. Thank-you.

Answer 1

I'm pretty sure you don't have thrombosis... thrombosis is a condition where you have blood clots floating around in your bloodstream, and the fact that your foot is *that* swollen and has purple and red all over makes me think there's an infection (or possibly bug venom as someone mentioned previously).

Make sure you talk to a doctor--if you do have an infection, it can get really bad really fast, and you can't really diagnose it from a website. If you notice it spreading or draining pus or anything indicating it's getting worse, go see a doctor as fast as you can.

Answer 2

I think that you are right.  It seems like this was some kind of necrotizing venom as your tissues seem to be breaking down.  The swelling is edema.  When your body responds to necrotic tissues the blood vessels in the area swell and become permeable to proteins and immune cells that need to get out of the blood and into the interstitial tissues for repair.  Albumin follows the proteins into the interstitium and causes the edema (swelling).  The discoloration is also part of the repair process though it is the result of the breakdown of iron containing molecules (much like what you see in a brooze).  In all, the symptoms that you are presenting are a sign of your body trying to repair necrotic tissue.  

You can only speculate on the culprit as you didn't see it.  Where were you when you felt the bite?  This can tell you a lot.  If you were in a dark place with wood such as a garage it may have been a black widow.  Of course this also depends on where you live.  To have a reaction such as the one you are having the bite had to be from something with potent venom.  I would search the internet to find a doctor who has some expertise in insect bites instead of wasting time with doctors who just guess.  It may be too late for an anti-venom, so you may just have to rely on your immune system to repair this tissue damage.  In the mean time, take plenty of Vitamin C as this helps with the lying down of collagen in the repair process.
