Hello..Hello well it's quite possible that you are facing muscular spasm... suggest you to use any analgesic spray for the time being... it's better you consult an orthopaedician and get yourself examined to r ule out causes related to spine or postural problems... As for the loosemotions generally we give loperamide if of non infectious type and also start with antibiotics like ornidazole with oflox and SPOROLAC to enhance the strength of gut...Thank you
