Accordingly I met Ortho surgen and taken Xray and Blood Test(CCBC, ESR, RBS, RA (QUANTITATIVE). All the reports was o.k. in the range. Xray report is with doctor only, but he said there is no fracture, but in side little scratch there. following medicines prescribed: (spelling error might be there) ACE PROXYVON gastracid liquid -opain -knee cap When I have seen the side effects of the Ace Proxyvon, I am very much tensed eventhough our doctor prescribed, for a 2nd opinion I was searchin on the internet, this is what I want to know...
