What is Superficial Thrombophlebitis and How Long Will it La

I had a superficial ThromboPhlebitis on Feb 21 at 6:45pm; 27 days after starting a new hormonal contraceptive (Nuvaring). I was given Compression stockings and 81 Mg Aspirin to deal with it. I was told there was no reason to stop hormonal contraception but I got scared and removed it 3 days later. I then had a series of pain that turned into streaks of spider veins down my thighs. I was, however, unable to see my PCP for 3 weeks. He said I was "fine" despite my continued pain, etc. He added 600 Ibuprofen b/c I have "inflamed veins". I felt bruised and exhausted for a month.

I am still having random sharp pain in localized areas & stinging, burning, and occasional itching up and down both arms & legs. There are times I get leg cramps or I will feel a sudden stinging (like a bee sting) and when I touch the area I find a firm vein... then it will go away 5 or 10 minuets later and the area will be sore for a day or 2. There are times I wake up and I feel like I am vibrating and my veins are all prominent but the Dr says that can't happen.

Is there something going on that I should be going to a different Dr, maybe a specialist? How long will this condition last? When should I be concerned? (My current Dr made me wait 24 hours after I had a rope-like vein on my inner thigh that developed a swollen patch 3 inches above it - then the US couldn't find anything.) I am frustrated with my care; the Dr walks out of the room if I begin to say anything and he doesn't ask or answer questions. I am anxious about the condition and what is going to happen to me. Can I try to exercise and get a massage or will I risk anything by doing that? I am trying to return to my normal life but I hurt so bad and I am afraid to do anything.
