I can't think of the name of it, but the lump on your foot may have been some sort of internal bleeding where the blood became gel. My grandmother had one on her thigh once from throwing her leg over a fence (my grandmother was adventurous, lol) and she had to have it lanced. My husband also got one following one of his surgeries as he had to work immediately after surgery. (I wish I could think of what it's called!)
I agree with the others that an MRI might shed some light on this problem. I have many problems that are not visible, or are only partially visible on x-ray. You may need to go to a foot pain specialist, as well. There are many things like neuropathy, plantars faciitis, and others that can cause pain. I also think it's likely you broke a small bone and they haven't been able to find it. Definetly keep pursuing the cause. You said you injured it at work orginally. Workman's comp should still cover the cost of finding out what's happened to you.
I hope you find out what's going on!
Really good input from Running Mom on how it could be your back. Very often things in the back travel to the leg and foot and injuries in the neck can travel to the arms and legs. Something else for the doctor to look at in ruling things in and out.
Could it possibly be coming from your back? Could you maybe have a pinced nerve from a slipped disc or maybe you have bone spurs caused by arthitis in your back as well. Maybe you need to have an MRI of your spine just in case there is. Usually when you have problems in the back spine, the pain travels to the legs and feet. Anyways, it's just a thought. Good luck and I hope you can find the cause.
Great point, Sara. My son also broke a small bone on the top of his foot and it took a while to find it. Sprains can often be much more painful than breaks and can take longer to recover from but at this point, if it was a sprain, I'd think you'd see improvement. There are also lots of other structures you could have injured, tendons, ligaments, and like Sara said, nerves. Maybe you need other tests besides x-rays? Maybe an MRI? And what kind of doctor are you seeing and where? Sometimes when we don't get relief from our local doctors it's a good idea to search out a specialist. And if the local specialist doesn't help, then beyond that. A specialist in a bigger institution, maybe a teaching hospital.
When I started having trouble with my hand, I saw an orthopedic. I thought he was okay and he did help the pain. Unfortunately, he probably made things worse. He gave me many cortisone shots, which did alleviate the pain, but you're only supposed to have so many and I had many more than I should have. As a result, the bones in my thumb joint sort of broke, shattered and crumbled a bit. My primary care doctor suggested I see not just an orthopedic but someone specializing in hands. That's all he does is hands. If I had seen him at the beginning, I probably would have had a better outcome.
The hands have lots of tiny bones, vessels, ligaments, tendons and nerves, and I imagine it's the same with the feet. You want someone who sees and deals with feet all the time; someone who may have come across something like this before.
Good luck. I hope you'll post and let us know how things are going. Lots of support here. It's been a God send to me to be able to chat with people who can understand what's going on.
I'm really sorry to hear you're in pain. Unfortunately we're not doctors here but pain patients. However we have some very smart members who may be able to shed light some light as to the source of your pain.
Are you certain there isn't a break in a bone in there somewhere? There are so many tiny bones in your foot. It took the drs 5 months to find the break in my foot. (This was many years ago. Ended up being a sesamoid bone on the bottom of my foot.) I'm telling you this because those breaks can be hard to find. Or it could be some type of nerve damage. I don't know.
My best advice is to see an orthopedic doctor. You may wish to consider wearing an ankle brace, available at CVS, Walgreens et al. Ice may help your swelling. But above all try to get in to see a doctor who can diagnose. Short of a diagnosis, you might want to see a pain management doctor. At least they can do something to help your pain.
Please stick around and check back later and tomorrow. I'm sure one of our member will be able to give you better advice than I.
