Right Heel pain. Can i do. pls suggest?

Bcoz of right heel pain When I get up in the morning I can't take few steps, but after a while it will be ok but now a days the pain is persistent all da day. From 2 days I'm feeling little pain in left leg too. Actually I don't use pillow n sleep on hard bed as I hav little back pain, shoulder pain n knee pain too I have taken Rabykem,sunflox,Acemiz-MR,Fynace-CQ,Holyvit-PG tablets after Doctor prescription n they r of no use to me n even more after leaving da tablets pain has increased. 2 years back I had some viral arthritis type fever after some medication I'm ok but not like fully back to normal in terms of flexibility n all. Though they don't obstruct my daily life I still have some pains in joints Shud I take Ayurvedic r allopathic medicine.. I'm confused Can I do exercises with weights to strengthen r Can I do Surya namaskaras r what yoga asanas n exercises can I do...pls suggest
