"Four hospitalisations in 40 days, physical pain, mental agony, changes you from inside. Strengthens resolve to come back," Tewari said in a post on social networking site twitter.
The minister was apparently referring to jibes by rival party leaders, who had said that Tewari was running away from contest Lok Sabha polls.
Tewari, who had won from Ludhiana Lok Sabha seat in the last General Elections, has not been fielded by his party which has nominated former Punjab chief minister Beant Singh's grandson Ravneet Singh Bittu as its candidate from the seat.
