I am a former jazz bassplayer and genetically all my family suffers from arthritis. Used to race on skis and as a result have both knees already replaced, thanks to wonderful technology, so I am walking, running and even cross country skiing. But lately I have started to experience numbness in my left hand (first), after driving longer distance. Now the numbness is in both hands, together with tingling, pins and needles and last few night I had to get up and move my arms to get a rid of severe pain in my both hands. My 96 years old father in Czechoslovakia just told me, that whole family went thru the same thing and my sister even had a carpal operation. But he claims, that it is a poor blood circulation and has a drops called "SECATOXIN FORTE", which after some time stopped all the symptoms. Do we have any medication compatible in US, because web site has a large number of articles about this drug, but all seems to be in Europe.(Czech republic.) Had several opinions: after effect from old whiplash, pinched nerve,etc., but my dad is adamant, that it is a blood circulation. (Experienced by 3 members of my family.) THIS IS A PLEA FOR HELP! Still need to play my bass, but sleepless nights, being awake from excruciating pain, are little too much, even compared to my both total knee replacement surgeries and also having hard time getting off PERCOCET. Anyone with similar problems? Are there any medications on US market?
