Hi and welcome to HCM
Pain in your foot could be due to flat feet (fallen arches) or planter fasciitis
. Little bump between your right ring toe and pinky toe could be growth from underlying tissue or benign growth. Thorough clinical evaluation, xray of foot and FNAC of bump might be helpful to diagnose the condition.
I do hope that you have found something helpful and informative and I will be glad to answer any further query.
