Bawaskar was born to Saluba and Rakhmabai in Dehed village (now in Bhokardan, Jalna, Maharashtra)^[3] He completed his schooling in Buldhana and worked in the farms, restaurants, temples, bookshops, the brick kiln, and held odd jobs to support his education.^[4][5]

After his studies in Nagpur, Bawaskar was appointed in 1976 to a government-funded primary health centre in Birwadi, in Raigad district.^[10] Over the next 40 years of medical career, Bawaskar spent most of his time in the rural Konkan region of Maharashtra, at the foothills of Western ghats.

At Birwadi, he witnessed high fatality rates of 8–40% due to the stings of Hottentotta tamulus scorpions; children being majority of the victims.^[11] The venom mainly affects the cardiovascular and pulmonary system, eventually leading to a pulmonary oedema, which may cause death. He compiled the findings and further tests were carried out at the Haffkine Institute in Mumbai. These latter stating these findings were published in The Lancet in 1978.^[12][13][14]

Bawaskar tried existing methods of symptomatic treatments with atropine, beta-blockers, chlorpromazine, and aminophylline.^[15] These methods however would not result in noticeable decrease in the death rates. Scorpion antivenom has little effect in clinical treatment but application of prazosin reduces the mortality rate to less than 4%.^{[16][17][18][19][20][21][22][23]}
