Patience over sickness
Ata bin Abu Rabaah reported that Ibn Abbas (radi Allahu anhum) asked him whether he would like that he should show him a woman who is from the people Jannah. When he replied that he certainly would, he said, “This black woman, who came to the Prophet (sal Allahu alaihi wa sallam) and said, ‘I suffer from epilepsy and during fits my body is exposed, so make supplication to Allah for me.’ He (sal Allahu alaihi wa sallam) replied, ‘If you wish you endure it patiently and you be rewarded with Jannah, or if you wish, I shall make supplication to Allah to cure you?’ She said, ‘I shall endure it.’ Then she added, ‘But my body is exposed, so pray to Allah that it may not happen.’ He (sal Allahu alaihi wa sallam) then supplicated for her.”
[Al-Bukhari and Muslim]
While continuing medical treatment, one should not ignore his prayer to Allah because both have importance and utility of their own.
And Allah Knows Best!
