I was diagnosed with a large DVT in my left leg about 7 months ago. Since then I have had intermittent double vision, chronic headaches, tingling in my hands(particularly my pinky), swollen painful tingling upper right abdomen. Also my joints,mainly my fingers and knees, have been hurting. I had an MRI of my brain and everything was normal. My doctor seems to think all my symptoms are nothing. Should I be worried or get a second opinion?
