Here are some passages relating to physical problems or suffering. They give some good things to think and meditate on.

5 ¶ Thus saith the LORD; Cursed be the man that trusteth in man, and maketh flesh his arm, and whose heart departeth from the LORD. 6 For he shall be like the heath in the desert, and shall not see when good cometh; but shall inhabit the parched places in the wilderness, in a salt land and not inhabited. 7 Blessed is the man that trusteth in the LORD, and whose hope the LORD is. 8 For he shall be as a tree planted by the waters, and that spreadeth out her roots by the river, and shall not see when heat cometh, but her leaf shall be green; and shall not be careful in the year of drought, neither shall cease from yielding fruit. 14Heal me, O LORD, and I shall be healed; save me, and I shall be saved: for thou art my praise. (Jeremiah 17:5-8,14 AV)
Deuteronomy 32:39 ¶ See now that I, even I, am he, and there is no god with me: I kill, and I make alive; I wound, and I heal: neither is there any that can deliver out of my hand.

Psalms 6:2 Have mercy upon me, O LORD; for I am weak: O LORD, heal me; for my bones are vexed.

Psalms 6:4 Return, O LORD, deliver my soul: oh save me for thy mercies’ sake.

Romans 9:20 Nay but, O man, who art thou that repliest against God? Shall the thing formed say to him that formed it, Why hast thou made me thus? 21 Hath not the potter power over the clay, of the same lump to make one vessel unto honour, and another unto dishonour?

1 O LORD, thou hast searched me, and known me. 2 Thou knowest my downsitting and mine uprising, thou understandest my thought afar off. 3 Thou compassest my path and my lying down, and art acquainted with all my ways. 4 For there is not a word in my tongue, but, lo, O LORD, thou knowest it altogether. 5 Thou hast beset me behind and before, and laid thine hand upon me. 6 Such knowledge is too wonderful for me; it is high, I cannot attain unto it. 7 ¶ Whither shall I go from thy spirit? or whither shall I flee from thy presence? 8 If I ascend up into heaven, thou art there: if I make my bed in hell, behold, thou art there. 9 If I take the wings of the morning, and dwell in the uttermost parts of the sea; 10 Even there shall thy hand lead me, and thy right hand shall hold me. 11 If I say, Surely the darkness shall cover me; even the night shall be light about me. 12 Yea, the darkness hideth not from thee; but the night shineth as the day: the darkness and the light are both alike to thee. 13 For thou hast possessed my reins: thou hast covered me in my mother’s womb. 14 I will praise thee; for I am fearfully and wonderfully made: marvellous are thy works; and that my soul knoweth right well. 15 My substance was not hid from thee, when I was made in secret, and curiously wrought in the lowest parts of the earth. 16 Thine eyes did see my substance, yet being unperfect; and in thy book all my members were written, which in continuance were fashioned, when as yet there was none of them. 17 ¶ How precious also are thy thoughts unto me, O God! how great is the sum of them! 18 If I should count them, they are more in number than the sand: when I awake, I am still with thee. 19 Surely thou wilt slay the wicked, O God: depart from me therefore, ye bloody men. 20 For they speak against thee wickedly, and thine enemies take thy name in vain. 21 Do not I hate them, O LORD, that hate thee? and am not I grieved with those that rise up against thee? 22 I hate them with perfect hatred: I count them mine enemies. 23 Search me, O God, and know my heart: try me, and know my thoughts: 24 And see if there be any wicked way in me, and lead me in the way everlasting. (Psalms 139:1-24 AV)

1 ¶ Therefore being justified by faith, we have peace with God through our Lord Jesus Christ: 2 By whom also we have access by faith into this grace wherein we stand, and rejoice in hope of the glory of God. 3 And not only so, but we glory in tribulations also: knowing that tribulation worketh patience; 4 And patience, experience; and experience, hope: 5 And hope maketh not ashamed; because the love of God is shed abroad in our hearts by the Holy Ghost which is given unto us. (Romans 5:1-5 AV)

19 Remembering mine affliction and my misery, the wormwood and the gall. 20 My soul hath them still in remembrance, and is humbled in me. 21 ¶ This I recall to my mind, therefore have I hope. 22 It is of the LORD’S mercies that we are not consumed, because his compassions fail not. 23 They are new every morning: great is thy faithfulness. 24 The LORD is my portion, saith my soul; therefore will I hope in him. 25 The LORD is good unto them that wait for him, to the soul that seeketh him. 26 It is good that a man should both hope and quietly wait for the salvation of the LORD. 27 It is good for a man that he bear the yoke in his youth. 28 He sitteth alone and keepeth silence, because he hath borne it upon him. 29 He putteth his mouth in the dust; if so be there may be hope. 30 He giveth his cheek to him that smiteth him: he is filled full with reproach. 31 For the Lord will not cast off for ever: 32 But though he cause grief, yet will he have compassion according to the multitude of his mercies. 33 For he doth not afflict willingly nor grieve the children of men. 34 To crush under his feet all the prisoners of the earth, 35 To turn aside the right of a man before the face of the most High, 36 To subvert a man in his cause, the Lord approveth not. 37 ¶ Who is he that saith, and it cometh to pass, when the Lord commandeth it not? (Lamentations 3:19-37 AV)

3 ¶ Blessed be God, even the Father of our Lord Jesus Christ, the Father of mercies, and the God of all comfort; 4 Who comforteth us in all our tribulation, that we may be able to comfort them which are in any trouble, by the comfort wherewith we ourselves are comforted of God. (2 Corinthians 1:3-4 AV)

2 I will go before thee, and make the crooked places straight: I will break in pieces the gates of brass, and cut in sunder the bars of iron: 3 And I will give thee the treasures of darkness, and hidden riches of secret places, that thou mayest know that I, the LORD, which call thee by thy name, am the God of Israel. (Isaiah 45:2-3 AV)

Thou tellest my wanderings: put thou my tears into thy bottle: are they not in thy book? (Psalms 56:8 AV)

For we wrestle not against flesh and blood, but against principalities, against powers, against the rulers of the darkness of this world, against spiritual wickedness in high places. (Ephesians 6:12 AV)

But let it be the hidden man of the heart, in that which is not corruptible, even the ornament of a meek and quiet spirit, which is in the sight of God of great price. (1 Peter 3:4 AV)

Be still, and know that I am God: I will be exalted among the heathen, I will be exalted in the earth. (Psalms 46:10 AV)

Come unto me, all ye that labour and are heavy laden, and I will give you rest. (Matthew 11:28 AV)
