intermittent claudication
"It took about 9 weeks of use for it to kick in , but the pain was then reduced by at least 90% making it bearable to wait out the tests and appointments and scans which have taken several months already to try to determine the cause. Only side effect is drowsiness and occasional nausea which lasts a few minutes . I can't seem to sleep enough to catch up.

I have been on it for 5 months now. Swelling suddenly came up in November 2015 and was finally prescribed Pentoxifylline in April 2016 after 5 months of real pain, then 2 more months before it took effect."
