I try topical L-arginine here
 

Given similitudes with nytroglycerin, i attempt 1 hour of topical l-arginine for tos's symptoms to evaluate his effectiveness and duration.

Evidences in litterature :

EDIT : I feel akward because i sudently realised that i can't evaluate because i'm pain free. I have an intermitent loss of strenght during activities, but can't evaluate with that.

If there is a volonteer to try arginine and post results...
