New to Reddit and DVTs

Hello fellow redditors, I am new to Reddit and this is my first ever post so please be kind. I was just diagnosed with a DVT in the peroneal vein of my right calf on the 6th in the ER. It was completely unprovoked and I’ve never had a blood clot before. The hospital really freaked me out when they told me there was a really low, but possible chance that it could “break loose” and go into my lungs. So a couple of days later, I was freaking out and went to a different ER this time because I was having shortness of breath. They also found the clot in the same spot. The first ER had started me on Eliquis and gave me an 18 day prescription for it while I got in with my doc. I followed up with my PCP and she said I would need to be on the Eliquis for at least 3 months. She told me I could resume normal activity, but just not to do any strenuous exercise or heavy lifting. But even my normal day to day just walking around the house was causing a lot of pain. So I ended up going back to the ER and had 2 more ultrasounds confirming that the clot had just gone away! In a week! My doctor said it was pretty amazing that it went away that fast, but she wants to keep me on the Eliquis still for 3 months. What I don’t understand is why I’m still having pain, even just from walking around the house. And my pain is in both legs and my knees and joints, not just where the clot was. As a matter of fact, I didn’t have your typical DVT symptoms. I was having pain in both legs, a rash on my legs when I was on my feet for too long, a low grade fever, and my white blood cell count and CK levels were high. The only reason they found the clot was because I asked them to check my D Dimer since it had been very high in the past. What can you take or do for the pain safely other than Tylenol? And are you allowed to go back to work or if just your normal walking around is causing pain, should you refrain?
