Acute Chest Pain, Blood Clot, Kidney Pain, Trembling Muscles, Pneumonia DVT. Installed IVC Filter. Treatment?
With the multitude of the problems involving more than two systems your issue is complicated and it does not have a simple answer.
With a risk of DVT (Deep venous thrombosis) and just out of hospital with an IVC (Intra vena cava filter) if I were your on call physician I would opt for an immediate triage at the ER now. I do not suggest you to wait.
IVC filter is put to prevent the lower limb clots to reach the most important organs like heart, lungs and brain. So it is by no means nullify the risk but reduce the complications of heart attack, stroke and lung infarction.
A reduced blood supply (clot) to an organ like kidney causes unbearable pain. It means a lot of salvage the organ before it dies off. It raises a suspicion further when you say the output is very little. We generally say to our patients that he / she has to pass urine at least once in 8 hours, else it is not normal.
Hope you understand the need to reach the ER immediately.
Regards.
