Prayer is not intended to replace any current treatment. Do Not quit taking medication until a doctor is seen or has confirmed healing.
Watch for healing, not for symptoms of sickness. Begin by doing what could not be done before.
Confess any unconfessed sin, it could be an obstacle or blocking faith. 1 John 1:9 "If we confess our sins, he is faithful and just to forgive us our sins, and to cleanse us from all unrighteousness."
Forgive others, unforgiveness can hinder prayers Mark 11:25 "And when ye stand praying, forgive, if ye have ought against any: that your Father also which is in heaven may forgive you your trespasses."
Sometimes there are demonic forces at work behind various sicknesses or conditions. They may be involved and must be expelled.
Any of these conditions above may be a problem if the healing manifestation is taking a long time.
