blisters like itchy bumps, beneath last left two toes only,

[msabid]

Hello
I'm 27 years old. 2 months ago I felt itchy on my left foot, I rubbed it and web like skin appeared between my last and 2nd last toes, it was itchy,  I applied olive oil thinking that it's fungal infection. After some time it recovered and reoccurd when I walked briskly. This time it was like a bump/ blister filled with watery fluid and severe itching too.it popped on its own after shower and walk.fluid came out mixed with blood. And the hole in skin due to rupture/ leakage seem to expose flesh.Mean water was pinkish instead of being clear,  and little painful. Doctor diagnosed it as fungal and gave me antifungal ointment which didn't work, I visited doctor again n this time he diagnosed it as bacterial and this time oinment seem to work ,my wound was dried and thick flaky skin was shedding and my skin was almost clear....after recovery new skin is somewhat pinkish, thinner and has mild wrinkles.... . but again after I walked for some time it reoccured and doctor gave me another antibacterial oinment..... its like a cycle between... .last toe n then 2nd last toe. Doctor can't give me any oral medication as I'm feeding my 4 months old baby....one thing more, after drainage of water itching is no more.
Any help...
