have been taking quinine sulphate 300mg tabs, for about 4 weeks for bad cramps in legs both at night and during day. I have got slight burning affect around virgina and the need to spend penny very often, i also feel as though i am leaking yet dont seem to be. Have got low burning ache in lower tum area. can you please tell me if this might be due to quinine as it has only been like this for about 2 weeks.
