Hi been having severe pain in my leg mainly calf and behind knee, since Monday .Although most of it feels heavy and sore now. Went to A&E last night and was give a d dimer test which came back as high. Was told I will need an ultrasound but prob won't be able to get in until Wednesday . Typical bank holiday. Was given six clexane injections to last me till the scan. But pain is alot worse today was hoping for advice on best pain relief. Thanks.
